While this isn't a perfect solution, all of our systems have been reconfigured
so that none of the temp space is in / (root).  Sun's brilliant idea of
providing temp directories in a filesystem that is way too small is rediculous.

So, the following is done:

    rm -r /tmp /var/tmp /usr/tmp
    mkdir /usr/tmp
    chmod 777 /usr/tmp
    ln -s /usr/tmp /tmp
    ln -s /usr/tmp /var/tmp

This should be done either as single user or right after booting as root, with
no other users on the system.  Obviously, do not have X windows running either.

Because we also ship a disk/tape subsystem with our configuration, a partition
has been set aside on the second disk and it gets mounted as /usr/tmp.  Be
sure and do a "chmod 777 /usr/tmp" after mounting it for the first time.

I have only run across one problem with this configuration, upgrading the
SunOS, using the install_upgrade (or whatever it is called).  It uses the
temp directories as if they were unique.  So, if the OS needs upgrading,
the links need to be removed and a mkdir done on each of them.  After the
OS upgrade is done, the links can be put back in place.  It isn't a real
pain and the OS isn't changed that often :-)
