change when /tmp is cleaned

[strycat]

I'm using Kubuntu 11.10 on my laptop. Every time I boot, the /tmp directory is cleaned. Is there a way to set that to every x days or every y boots? I looked for tmpwatch in the cron directories but it doesn't appear to be there.

Thanks in advance.

Did you happen to move your /tmp to a temporary file system (in /etc/fstab)? That is a common tweak, but the downside is that since a temporary files system is only stored in RAM, as soon as you shutdown or reboot, it is gone.

You can change the TMPTIME value in /etc/default/rcS
The default is "0", clear everything on every boot. A positive value like "7" will not clear files that are newer than seven days (this of course applies only if you have /tmp on disk rather than in ram).

If you want to save temp data across boots, it's often better to use /var/tmp instead of /tmp.
