Sorry I didn't respond to this sonner, but I've had the flu and haven't
been checking my e-mail.

Not until just now :-)
Hmmm..... You are correct. Odd. I guess it is supposed to just be a
mount point? That makes a bit of sense, but is also strange since if it is
trying to put users there, you'd think they would have a partition to mount
there by default? OK, I see from what is below what is going on with
automount. I wonder when they changed this? My other Solaris 8 machines
aren't set up this way (including ones that were not upgrades from
previous versions of Solaris), but I have always did my own install and
not used "out of the box" Solaris and may have overridden these defaults
without realizing this.
For those who are wondering this is what I get when I try a mkdir (BTW, I
have done no configuration on this machine yet - it is straight out of
the box).
# cd /home
# mkdir test
mkdir: Failed to make directory "test"; Operation not applicable

# useradd -D

#
So it is trying for /home, but I by default I don't have anything but
(what looks like an apparent) [auto]mount point?

/etc/auto_home is basically empty.
# more /etc/auto_home

automountd is running by default - it is just not configured to automount
anything :-)
# ps -aef | grep automountd

I take my bad Sun comment back. Good Sun.

I don't care what they intend, I need users to have a home directory -
and luckily with *NIX I can do what they don't intend :-). Actually, I
probably will keep it like this for a while just to see how it works. I
just will need to look into this auto_home thing a little more. Maybe I'll
use it and make the home directory NFS from a different Solaris box -
which from what I think you are saying is the intended way?
