Bug#373786: /etc/cron.daily/exim4-base should unset TMPDIR

[Piotr Kaczuba]

Package: exim4-base
Version: 4.62-1
Severity: normal

/etc/cron.daily/exim4-base should unset TMPDIR, so when one is using pam_tmpdir, the cron script could sucessfully do its work. The cron script uses find with chuid, and as a result tempnam() fails because it doesn't have access to the temp directory set by pam_tmpdir.

Below is the error message of /etc/cron.daily/exim4-base:

/etc/cron.daily/exim4-base:
tempnam: Permission denied
run-parts: /etc/cron.daily/exim4-base exited with return code 1
