Per user tmp?

[Gilboa Davara]

Hello all,

Any idea how I can setup a per-user tmp directory?
E.g.
USER1 has /tmp -> /tmp/USER1, /var/tmp -> /var/tmp/USER1.
USER2 has /tmp -> /tmp/USER2, /var/tmp -> /var/tmp/USER2.
etc.

In short, I want each user to have a private /tmp, and /var/tmp -
without having to resort to using virtualized/jailed environment.

Another approach is polyinstantiation. See:

Interesting read.
Thanks.

One thing I have done is create a tmp directory in each user's home
directory, and then set the TMP variable to point to it. You will
also want to add the tmp directory to /etc/skel so new users get it
created for them automatically. (I added "TMP=$HOME/tmp" and added
TMP to the export list in .bashprofile, but you could also add files
to /etc/profile.d to cover both the c and sh shell variants.

OH yes, the /tmp directory does limit what other users can do to
your files in /tmp.
