Re: [PLUG] Two passwd files?

That idea may work. Either post-processing or pre-processing the passwd 
file.
I had a similar idea for the hosts file. (Oh, I just realized how 
important it will be to modify the hosts file before distributing it!) 
I thought of getting a list of hosts from the hosts file, which 
requires removing comments and local host information, that the rsync 
script can use to automactically target its updates. On the client 
side, local host information will need to be preseved.
I'm starting to wonder if going back to NIS would be easier.

I want to use rsync and ssh to push the passwd file (and others) as an 
alternative to NIS. The question is, is it possible to have a "local" 
passwd file as an extension to the pushed passwd file? For example, to 
have a local root account which is only valid on a particular machine?
The config that I will be using is a variation of the approach detailed 
at http://www.ussg.iu.edu/security/rsync.html 

You could post-process locally with sed to change the root line:
On local host:
 ssh $central:/etc/passwd /etc/passwd.template
 sed < /etc/passwd.template > /etc/passwd.root script
 mv /etc/passwd.root /etc/passwd
Assuming your constitution can take all this moving about without
excessive adrenaline or high blood pressure. Needless to say, you
want to make sure an error at one step of the chain can't leave you
without a passwd file.
