1. The installation guide says to get a mopd from ftp.stacken.kth.se:/pub/OS/NetBSD/mopd -- however, this machine is long dead. (I know how to build myself a mopd, but it's nice if the install documents tell the truth for a new user.)
Hm, that is the master distribution. Need to check with Stacken where it has gone today.
2. The netboot/ directory that gets built these days has four files in it, boot, boot.mop, install.ram.gz, and install.ram.symbols.gz — it is unclear what install.ram.gz etc. are for. The install docs mention a netbsd.ram.gz but that's not in the directory and it isn't clear if these are the same, or what the "ram" in the name indicates.
Heh, that is probably an ancient typo. They are the same, yes.
3. The guide claims that there is a a directory called installation/misc that contains "Miscellaneous vax installation utilities; see installation section below." -- this directory does not appear to exist and no further reference is made to it.I wonder it did exist at some point long ago; there's all sorts of standalone utilities we shipped for most ports 30 years ago to aid in installation. The process used to be that after the release got auto-built that the portmaster would copy those things in to the release. (This lack of automation was probably a mistake and was probably my fault.)
That directory have never existed. I assume that text have appeared in some aligning of the install docs with some other port.
For the VAX in particular, there seem to be a bunch of utilities of various kinds kicking around in src/sys/arch/vax that might have been part of 4.4 or our stuff at one point long ago.
