Debian packages relying on TMPDIR
I'm not sure if this has previously been discussed on
debian-devel but I haven't found anything. I have
encountered some packages which when started as root and
drop privileges rely on the TMPDIR environment variable.
That is $TMPDIR must be writable. This is a problem here
as I'm sure it is on other systems. I have my $TMPDIR set
to /root/.tmp for security and that directory is mode 0700.
If I upgraded MySQL for example and dpkg restarts it, it
inharits my secure TMPDIR but MySQL drops root privilege
and cannot write to it.
I am wondering if it is my responsibility as a user to
clear TMPDIR on a dist-upgrade, the init.d script to clear
it or the upstream program to check to see if it's writable
and use /tmp if not.
