Re: Moving /tmp to tmpfs is fine

Yes, per-user temp directories is a good idea.  Installing the
libpam-tmpdir package enable this by default, and beside some problems
with the root user (bad TMPDIR is inherited when I restart services
using /etc/init.d/ scripts), it work well.  Perhaps it should be
extended to allow the directory to be below ~/ instead of below
/tmp/. :)

It make it very easy to spot the programs not respecting $TMPDIR. :)

This sound a bit more scary, yes.
