root runs out of space



Hi,
My root directory is sitting on /sda1 and has only 1 GB. Now I often get
"disk full" massage because the /tmp directory is sitting in it. Is there a
way I can allocate some space from other part of pertitions to root
directory without re-installation? Or can someone show me how to re-direct
the /tmp onto a different pertition?
Thanks,
SW.
