  Similar to /tmp/, there is no reason to keep any leftovers in /var/tmp,
nor can any application expect content placed there to be persistent.

On several IPFire installations I have access to, this would remove
quite some clutter accumulated in /var/tmp over the years.

In that case, should ISO backups use a directory other than
"/var/tmp/backupiso"?

Thanks,

Hello Peter, Hello List,

I have to decline this patch because the IDS system currently stores
the downloaded tarballs (which contains the rules of a provider) in
that directory.

Each time the ruleset is altered or updated, these tarballs will be
decompressed and the required files are extracted from them.

So cleaning up this directory, would remove the tarballs and currently
breaks the entire IDS.

We might have to think about keeping this tarballs or to move them to a
different (better) location.

Best regards,

-Stefan

Hello everyone,

I agree with Paul and Stefan here. We should move things out of there first before we add this directory to the tidy up at boot time.

Who would like to grab this and work on this?
