Thank you all for getting back to me so soon regarding this question. I
guess I goofed by forgetting to tell you all that my machines here run
SunOS 4.1.3 and 4.1.4.

The concensus is that /tmp should not be on the root partition, and ideally
should be a partition of its own. All of you modern-folks running Solaris
:) informed me that the /tmp partition is, by default, a tmpfs and is
shared with the swap space and need not even be worried about. If one were
inclined to do the same on a SunOS machine, one would merely have to
uncomment a line in the rc.local init script. That as well as play around
with the fstab, modify the kernel, etc.

There were only one a couple of people who didn't see anything wrong with
putting the /tmp partition on its own disk (or even mentioned it as an
alternative), one of whom qualified it by saying that if one were to boot
up and the /tmp disk was broken or inactive and the system was in normal
operations, things shouldn't be too bad, since instead of writing to the
/tmp *disk* the OS would just write to the mount point, /tmp; and in single
user, this shouldn't be a problem.

For my purposes, at least, I think I can live with /tmp just pointing to
/var/tmp where /var is a partition on the same disk as root.

Thank you all again, I greatly appreciate your help,
