swinstall -s - # Minimum unambiguous invocation.
swinstall installs a POSIX distribution from a source archive to a
target directory. A POSIX distribution is a package, typically a
compressed tarball with metadata files in the prescribed file layout.
Neither swinstall nor any component of swbis is required on the target
host, however, the target host must look like a Unix system at the
shell and command-line utility level and have a POSIX shell. Remote
network connections are made by ssh. Ssh is the default but rsh can be
selected by a command line option.
By default and with no external influences (i.e. swdefaults file)
swinstall will read an archive on stdin and install all products and
filesets of package in "/" directory on the target host. An alternate
root may be specified using the target syntax. The distribution source
directory (swbis default: stdin) is selectable via the defaults file,
therefore it should be specified in uncontrolled environments.
swinstall operates on cpio or tar archives. swinstall supports cpio
archives by first translating to tar format, therefore, to reduce the
data transformations performed by swinstall, distributors encouraged to
deliver products in tar format.
swinstall will create an entry in an installed software catalog. This
is a directory usually located at /var/lib/swbis/catalog. Using this
information checks for upgrade, downdate, dependencies, and
reinstallation are made.
-f FILE
Reads software_selections from FILE. (Not implemented).
-p
Preview the operation. Depending on the verbose level
information is written to stdout. The target is not modified
although a remote connection is established.
-r
This option has no affect.
-s SOURCE
Specify the source file SOURCE, "-" is standard input. The
syntax is the same as for a target. SOURCE may be an archive
file or stdin.
-t targetfile
Specify a file containing a list of targets (one per line).
-x option=value
Specify the extended option overriding the defaults file value.
-X FILE
Specify the extended options filename, FILE, overriding the
default filenames. This option may be given more then once. If
the resulting specified value is an empty string then reading of
any options file is disabled.
-v
Given one time it is identical to -x verbose=2. This option can
be given multiple times with increasing effect. (Implementation
extension option).
-v is level 2, -vv is level 3,... etc.
level 0: silent on stdout and stderr.
level 1: fatal and warning messages to stderr.
-v level 2: level 1 plus a progress bar.
-vv level 3: level 2 plus script stderr.
-vvv level 4: level 3 plus events.
-vvvv level 5: level 4 plus events.
-vvvvv level 6: level 5 plus set shell -vx option.
-vvvvvv level 7 and higher: level 6 plus debugging messages.
--version, -V
Show version (Implementation extension)
--help
Show help (Implementation extension)
-W option[,option,...]
Specify the implementation extension option.
Syntax: -W option[=option_argument[,option...]
Options may be separated by a comma. The implementation
extension options may also be given individually using the
'--long-option[=option_arg]' syntax.
-W preview-tar-file=FILE
This is a testing/development option. Writes the fileset
archive to FILE. This is the same data stream that would have
been loaded on the target. This option should only be used with
the '-p' option. The output sent to FILE is a tar archive but
without trailer blocks.
-W remote-shell=NAME
Defaults File Option: swbis_remote_shell_client
This is the remote connection client program on the management
(originating host). The path NAME may be an absolute path (not
located in $PATH). The basename of NAME is used for
intermediate hops. Supported shells are "ssh" and "rsh". The
default is "ssh".
-W quiet-progress
Defaults File Option: swbis_quiet_progress_bar Disable progress
bar, which is active for verbose levels 2 and higher (i.e. -v).
-W show-options-files
Show the complete list of options files and if they are found.
-W show-options
Show the options after reading the files and parsing the command
line options.
-W pax-command={tar|pax|star|gtar}
Set the portable archive command for all operations. The
default is "pax".
-W pax-read-command={tar|pax|star|gtar}
Set the read command for local and remote hosts.
-W remote-pax-read-command={tar|pax|star|gtar}
Defaults File Option: swbis_remote_pax_read_command
Set the read command for remote hosts. This is the command that
runs on the target (e.g. pax -r, tar xpf -). The default is
"pax".
-W local-pax-read-command={tar|pax|star|gtar}
Defaults File Option: swbis_local_pax_read_command
Set the read command for local hosts. This is the command that
runs on the target (e.g. pax -r, tar xpf -). The default is
"pax".
-W pax-write-command={tar|pax|star|gtar|swbistar}
Set the write command for local and remote hosts. This is the
command that runs on the target (e.g. pax -w, tar cf -).
-W remote-pax-write-command={tar|pax|star|gtar|swbistar}
Defaults File Option: swbis_remote_pax_write_command
Set the write command for remote hosts.
-W local-pax-write-command={tar|pax|star|gtar|swbistar}
Defaults File Option: swbis_local_pax_write_command
Set the portable archive write command for local host
operations. This is the command that runs on the source (e.g.
pax -w, tar cf -). The default is "pax".
-W remote-pax-write-command={tar|pax|star|gtar|swbistar}
Defaults File Option: swbis_remote_pax_write_command
Set the portable archive write command for remote host
operations. This is the command that runs on the source (e.g.
pax -w, tar cf -). The default is "pax".
-W no-defaults
Do not read any defaults files.
-W no-remote-kill
Defaults File Option: swbis_no_remote_kill
Disables the use of a second remote connection to tear down the
first in the event of SIGINT or SIGTERM or SIGPIPE. Only has
effect if the number of ssh hops is greater than 1. A single
host remote connection (ssh hop = 1) never uses a second remote
connection.
-W no-getconf
Defaults File Option: swbis_no_getconf
Makes the remote command be '/bin/sh -s' instead of the default
'PATH=`getconf PATH` sh -s'.
-W shell-command=NAME
Defaults File Option: swbis_shell_command
This is the interactive shell on the target host. NAME may be
one of "detect" "bash", "sh", "ksh" or "posix" and specifies
the remote command run by the remote shell. "posix" is
'PATH=`getconf PATH` sh -s', "bash" is "/bin/bash -s", "sh" is
"/bin/sh -s", and "ksh" is "ksh -s". The default is "detect".
-W use-getconf
Opposite of --no-getconf.
-W allow-rpm
Defaults File Option: swbis_allow_rpm
Enable automatic detection, translation to POSIX format, and
installation of RPMs.
-W pump-delay1=NANOSECONDS
Adds a NANOSECONDS delay (999999999 nanoseconds ~ 1 second)
every ADJSIZE bytes in the file data byte pump. A delay of
10111000 nanoseconds (~1/100th second) is added for 2-hop or
greater target (i.e more than 1 remote host in the target spec).
This is a work around for a bug in OpenSSH [or Linux kernel]
that is seen for multi-hop installs where the intermediate host
is a Linux kernel. If 2-hop install fails, try it again, you
may get lucky, or, increase this delay, or, use ssh protocol
version 1 by using ''--ssh-options=1'', or try a 2-hop install
where the middle host is BSD. To disable delay for multi-hop
targets specify zero. For more information about this bug see
the README file from the source distribution.
-W burst-adjust=ADJSIZE
ADJSIZE is the pumped data size, in bytes, between the
NANOSECONDS delays. This is a work around for a bug in OpenSSH
or the Linux kernel that is seen for multi-hop installs where
the intermediate host is a Linux kernel. The default is 72000
for 2-hops or greater, and zero for single hop and localhost
installs.
-W ssh-options=OPTIONS
ssh client program options. For example -W ssh-options=1 sets
the '-1' ssh client option which specifies protocol version 1.
-W source-script-name=NAME
Write the script that is written into the remote shell's stdin
to NAME. This is useful for debugging.
-W target-script-name=NAME
Write the script that is written into the remote shell's stdin
to NAME. This is useful for debugging.
software_selections
Refers to the software objects (products, filesets) on which to
be operated. This is not implemented, however, specification of
a location and qualifier are supported. location allow
specification of a alternate relative root path within the
target path, and qualifier allows specification of a user-
selectable modifier. For example:
swinstall q=exp @ 192.168.1.1 # Tag the package as experimental
swinstall l=/unionfs/somepackage-1.0 @ 192.168.1.1 # Allows multiple
# packages with same tag to exist in the
# same target path, where the location
# disambiguates.
target
Refers to the software_collection where the software selections
are to be applied. Allows specification of host and pathname
where the software collection is to be located. A target that
contains only one part is assumed to be a hostname. To force
interpretation as a path, use an absolute path or prefix with
':'. The default target path for 'swinstall' is always '/'.
Source and Target Specification and Logic
Synopsis:
Posix:
host[:path]
host
host:
/path # Absolute path
Swbis Extension:
[user@]host[:path]
[user@]host_port[:path]
:path
Swbis Multi-hop Target Extension:
# ':' is the target delimiter
# '_' delimits a port number in the host field
[user@]host[@@[user@]host[@@...]][:file]
[user@]host_port[@@[user@]host[@@...]][:file]
# Using ':', a trailing colon is used to
# disambiguate between a host and file.
# For Example,
:file
host:
host
host:file
host:host:
host_port:host_port:
host:host:file
user@host:user@host:
user@host:user@host:host:
user@host:user@host:file
A more formal description:
target : HOST_CHARACTER_STRING ':' PATHNAME_CHARACTER_STRING
| HOST_CHARACTER_STRING ':'
| HOST_CHARACTER_STRING
| PATHNAME_CHARACTER_STRING
| ':' PATHNAME_CHARACTER_STRING # Impl extension
;
PATHNAME_CHARACTER_STRING must be an absolute path unless
a HOST_CHARACTER_STRING is given. Allowing
a relative path is a feature of the swbis
implementation.
NOTE: A '.' as a target is an implementation
extension and means extract in current
directory.
NOTE: A '-' indicating stdout/stdin is an
implementation extension.
NOTE: A ':' in the first character indicates a filename.
This is an implementation extension.
HOST_CHARACTER_STRING is an IP or hostname.
Examples:
Copy the distribution /var/tmp/foo.tar.gz at 192.168.1.10
swcopy -s /var/tmp/foo.tar.gz @192.168.1.10:/root
Implementation Extension Syntax (multi ssh-hop) :
Syntax:

# Note: a trailing ':' forces interpretation
# as a host, not a file.
wtarget : wtarget DELIM sshtarget
| sshtarget
| sshtarget DELIM
;
sshtarget : user '@' target # Note: only the last target
| target # may have a PATHNAME, and only a host

Installation consists of an analysis phase and an execution phase.
Analysis Phase
The installed software catalog is queried and checks are made to detect
reinstallation, downdating (installing an older version). Dependency
tests are made at this point. If these checks pass or are overridden
by options, then the installed software catalog entry is created
(moving the old entry). The checkinstall script is exectuted. This
script should be non-interactive, idempotent, and read-only from the
system's perspective. This script may exit with status of 0,1,2, or 3.
If the exit status is 3 (or 1) installation is rejected and the
installed catalog is restored.
Execution Phase
The preinstall script is executed, the fileset files are loaded by the
system tar utility and postinstall is executed.
o Execution Script Environment
swinstall sets certain enviroment variables during execution. The
values set are hard-coded in the control.sh script generated by
swinstall.
For example, execution of the postinstall script in package
foobar-1.0.tar.gz with the following layout
foobar-1.0/
foobar-1.0/catalog/
foobar-1.0/catalog/INDEX
foobar-1.0/catalog/dfiles/
foobar-1.0/catalog/foobar/
foobar-1.0/catalog/foobar/pfiles/
foobar-1.0/catalog/foobar/pfiles/INFO
foobar-1.0/catalog/foobar/pfiles/postinstall
foobar-1.0/catalog/foobar/bin/
foobar-1.0/catalog/foobar/bin/INFO
installed with the following command:
swinstall -x installed_software_catalog=/var/software/catalog \
@ /mnt/test
will result in the following environment (among others, inspect
control.sh):
SW_PATH=/bin:/usr/bin
SW_ROOT_DIRECTORY=/mnt/test
SW_CATALOG=var/software/catalog/foobar/foobar/1.0/0
SW_CONTROL_TAG= postinstall
SW_CONTROL_DIRECTORY=/mnt/test/var/software/catalog/\
foobar/foobar/1.0/0/export/foobar-1.0/catalog/foobar/pfiles
SW_SESSION_OPTIONS=/mnt/test/var/software/catalog/\
foobar/foobar/1.0/0/session_options
SW_PATH is constructed using getconf(1) to locate the posix level
utilites, otherwise it is the same as PATH.
If the interpreter attribute from the INFO file, is 'sh' or unset, the
executed shell interpreter is /bin/bash, sh as found in the PATH
specified by getconf(1), or /bin/sh in this order.
As of swbis-1.12 (Version 1.12), control script execution begins with a
current working directory ($PWD) of SW_ROOT. Prior to version 1.12,
initial current working directory was equivalent to
$SW_ROOT/$SW_CATALOG.
The form or format of an installed software catalog is not specified by
the ISO/IEC spec although it does specify an interface to it (e.g.
swlist utility) and operations on it.
This implementation creates a de-facto installed software catalog
rooted at the file system path specified by the value of the
installed_software_catalog extended option. The catalog is a file
system hierarchy containing regular files and directories.
The catalog is typically located relative to the target path. As of
swbis version 1.5, the catalog location may be specified using the file
URL syntax to indicate an absolute path. Any other form, such as an
unadorned absolute UNIX path will be treated as a path relative to the
target path.
For Example:
Below are example values of the installed_software_catalog extended
option found in the swdefaults file usually located in
$HOME/.swbis/swdefaults
var/lib/swbis/catalog # Default, relative to target path
/var/lib/swbis/catalog # Same, leading slash not respected
file://localhost/var/lib/swbis/catalog # Really absolute
file:///var/lib/swbis/catalog # Note triple leading slash

<path>/<ISC>/<bundle>/<product>/<pr>/<sequence_number>/location
<path>/<ISC>/<bundle>/<product>/<pr>/<sequence_number>/qualifier
<path> is the target path. <ISC> is the value of the
installed_software_cataglog extended option. <bundle> and <product>
are bundle and product tags. If there is no bundle in the distribution
the product tag is used. <pr> is the product revision. Other items
are explained below.
CATALOG LOCATION
/<path>/
/<path>/<installed_software_catalog>/
/<path>/<installed_software_catalog>/...
* Root or Alternate Root
/<path>/
<path>/ is the target path specified in the target syntax. By default
"/".
* Catalog Relative Root Directory
/<path>/
/<path>/<installed_software_catalog>/
<installed_software_catalog>/ is the value of the extended option by
the same name. By default "var/lib/swbis/catalog".
PACKAGE CATALOG RELATIVE ROOT
/<{bundle|prod}.tag>/<prod.tag>/<prod.revision>/...
In other words, if 'product' and 'bundle' refers to tags, and
product_revision is the value of the product.revision attribute then
the path segment is:
/bundle/product/product_revision
CATALOG SEQUENCE NUMBER
/<sequence_number>/
/<sequence_number>/...
sequence_number is a decimal integer starting with '0'. It is chosen
by swinstall to be unique at the time of installation.

export/...
export/catalog.tar
export/catalog.tar.sig
export/catalog.tar.sig2
...
export/catalog.tar.sigN
The export/ is a file system directory and its name is constant for all
packages and is unique to the swbis implementation. The
export/catalog.tar file is the signed file from the POSIX distribution.
The export/catalog.tar.sig file is the signature file from the
distribution. If there is more than one signature, then it is the last
one. export/catalog.tar.sig2 is the next to last signature, and
export/catalog.tar.sigN is the first one, where N is the total number
of signatures.
INSTALLED -- The state metadata file
<sequence_number>/INSTALLED
The INSTALLED file is similar to an INDEX file in its grammar and
syntax. Unlike an INDEX file, it may contain control_file definitions.
The INSTALLED file stores the control script return codes and fileset
installation state. It is updated several times during the operation
of 'swinstall'. It can be parsed using libexec/swbisparse and the
'--installed' option.
control.sh -- The master control script
<sequence_number>/control.sh
SYNOPSIS: control.sh tag_spec script_tag
The control.sh file is a POSIX shell script that is automatically
generated by swinstall. It provides a common interface for control
script execution. Its primary purpose is to set up the script's
execution environment and map script tags to the control script
pathnames. It assumes that 'export/catalog.tar' is unpacked in
export/.
session_options -- The extended options
<sequence_number>/session_options
This file contains the extended options in a form that may be executed
by the shell '.' (dot) command. It is automatically generated by
swinstall. The value of the SW_SESSION_OPTIONS environment variable is
the absolute pathname of the this file.
EXAMPLE CATALOG ENTRY
Below is an example entry of the catalog created by swbis version
0.405. In this example, the target path is '/mnt/test', the
installed_software_catalog is '/var/lib/swbis/catalog/', the bundle tag
is 'foobare', the product tag is 'foobare-doc', and the product
revision attribute is '0.902'.
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/export
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/export/catalog.tar
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/export/catalog.tar.sig
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/INSTALLED
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/control.sh
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/vendor_tag
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/location
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/qualifier
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/0/session_options
A deleted old catalog entry begin with '_', for example
/mnt/test/var/lib/swbis/catalog/foobare/foobare-doc/0.902/_0/...
Although swinstall does not depend on the file name as this
accommodates installing from standard input, a typical name for this
package would be:
foobare-doc-0.902-sl04.tar.gz
where 'sl04' is the vendor tag.
Software Specification Targets
A dash '-' is supported and means stdout or stdin. Operations with
stdout and stdin on a remote host is not supported.
A decimal '.' is supported and means the current directory. This is
supported for remote and non-remote targets. If the source is standard
input, the distribution will be unpacked (e.g. pax -r) in the directory
'.'. If the source is a regular file then a regular file in '.' will
be created with the same name.
RPM Translation
RPM (RedHat Package Manager) format packages are installed by first
translating to an equivalent ISO/IEEE file layout in POSIX tar format
and then installing as a POSIX package. This translation and detection
is transparent to the user if the ''--allow-rpm'' option is set in the
command line args or the swbis_allow_rpm is set to "true" by the
defaults files, otherwise an error occurs.
Since translation is done on the local (management) host, RPM is not
required on the remote (target) host.
The translation is (internally) equivalent to :
cat your-0.0-1.bin.rpm |
/usr/lib/swbis/lxpsf --psf-form2 -H ustar |
swpackage -W source=- -s @PSF | swinstall -s - @/
Testing with RPM
To test the swbis components, a completely independent means to
install and verify a package is needed. RPM provides this means and
can be used in the following way:
rpm -i --nodeps --force your-0.0-1.i386.rpm # Install
rpm --verify --nodeps your-0.0-1 # Show that all is well
rpm -e --nodeps your-0.0-1 # Remove it.
rpm -i --nodeps --justdb your-0.0-1.i386.rpm # Install just the database.
rpm --verify --nodeps your-0.0-1 # Shows the files are missing.
swinstall --allow-rpm -s - < your-0.0-1.i386.rpm
rpm --verify --nodeps your-0.0-1 # Show that all is well again
Extended options can be specified on the command line using the -x
option or from the defaults file, swdefaults. Shown below is an actual
portion of a defaults file which show default values.

swinstall.swbis_install_volatile=true
swinstall.swbis_volatile_newname= #empty string, e.g. ".rpmnew"
0 if all targets succeeded, 1 if all targets failed, 2 if some targets
failed and some succeeded.
Multiple ssh-hops is an implementation extension.
The swbis distributed utilities require bash, public domain ksh, or
ksh93 (version 2009年05月05日), or Sun's /usr/xpg4/bin/sh to be present on
the target host. If the swbis_shell_command extended option is set to
'detect' you don't have to know which one is present, otherwise you may
specify one explicitly.
A POSIX awk is required, and with the ability to specify several
thousand bytes of program text as a command argument. GNU awk works,
as does the ATT Awk book awk, and the awk on BSD systems. See the
INSTALL file for further details regarding a small issue with the
OpenSolaris (c.2006) awk.

swinstall is subject to breakage if a user's account on an intermediate
(or terminal) host in a target spec is not configured to use a Bourne
compatible shell. (This breakage may be eliminated by use of the --no-
getconf option as explained above.)
A multiple ssh hop source spec (more than 1 remote host involved in
the source transfer) upon a SIGINT may result in sshd and ssh processes
being left on on the intermediate host(s), this despite, swinstall's
action of sending a SIGTERM to the remote script's parent process.
swinstall does not currently implement Software Selections, not fileset
dependencies, and much more. Only packages with one product and one
fileset are supported.
