I am developing a network install procedure for AIX PS/2 1.2 for our
Athena enviroment, which doesn't use TCF at all.  That is, each AIX
PS/2 machine is a self-contained site with all its files resident.
Essentially, operations staff simply want to bring up a machine using
only a few floppies.  It's been fairly easy to insinuate my changes
into the stereotyped install procedure so far, and the procedure is
fairly straightforward:

	boot from floppies using kernel with TCP/IP enabled
	use standard install diskette
	use customized "operating system" diskette (yes, one)
	mount (NFS or Athena RVD) an archival hierarchy of an installed system
	copy over machine-independent files (i.e., not those
		custom-created by the install procedure: /local/site,
		/local/filesystems...)

Now at this point the resulting machine should look like a machine
which has been installed from all 60+ floppies.  And it does, sorta.
However, when I boot from hard disk, it appears that /sitename is mounted
read only (although "mount" doesn't report that.)  Attempts to run
fsck fail ("can't create pipe for first/second fsck").  And, as you
know, it's impossible to unmount /sitename.  The root is writable.
Coming up on the maintenance disk, neither the root nor /sitename
are "dirty"--that is, the install procedure unmounts and reboots cleanly
and fsck's done from the maintenance disk don't report any modifications.

I think I must be simply forgetting something simple.  I was hoping that
a Locus person might read this and quickly have a few suggestions.
