I suggest using /var/tmp/tmp on a Debian system if you want to do this.
That allows scripts that clean up /tmp to not clean /var/tmp (which may
have things you want to last longer).

I tried that on 2.4.4 and I couldn't run the KDE. It seems that tmpfs
doesn't do all the things that a real FS does (yet).

Hasn't caused any great problems for me. Although on systems with
separate file systems for /var and /var/tmp it means that I need to run
mount three times before I can edit a file in the root FS.
Another thing that no-one seems to be considering is the "--bind" option
to recent versions of mount (only works on 2.4 kernels).
