stopping /tmp cleanup on reboot
 
I just updated a system to lucid and discovered that /tmp is being emptied
on reboot. I recall this happening when I upgraded to karmic, but it was
easy to find where this was happening and comment it out ins some startup
script or other. But I haven't been able to find the right script in lucid.
Does anyone happen to know where the command is located so I can comment it
out?

FWIW, I found my notes... in the past, /tmp was emptied during execution of
a script called bootclean.sh. It was a simple matter to comment out a line
in that script.

But it seems that in lucid bootclean.sh no longer exists, so I need to know
which file now does the job of emptying /tmp, so I can stop it doing so.

It's done the way it's always been done... ;-)
In /etc/default/rcS edit "TMPTIME" to "infinite"

Google seems to show that you need to edit the file /etc/default/rcS
and change
TMPTIME=0
to
TMPTIME=-1

0=always empty, A positive number specifies the number of days
between emptying, and a -1 disables it altogether

Thank you, sir (and Reinhold too).

Karmic wasn't supposed to keep files in /tmp.

I wonder why you want to keep /tmp at boot. This has led to problems for me in
the past (not being able to start X)
For this reason, my /tmp is mounted as tmpfs. There is a blueprint to make
this the default.

I've experienced the bug myself - however, e.g. konqueror uses/used
some file in /tmp to detect crashes and restore itself after one.
That would be pretty difficult if /tmp was emptied on every boot.

I also sometimes find it useful to examine the temp files some apps
produce, especially over a couple of days.
