Please note that this is the DEFINED behaviour of /tmp, so it has a very
high probability of happening.
If you want temporary data to survive a reboot, put it in /var/tmp.
Oh - and if SeLinux only lets you put it in /tmp, what happens if you
don't have a separate /tmp partition? You can't put the backup file on
the partition you are rebuilding, and SeLinux won't let you put it
anywhere else? That's a big disaster in the making ...
Cheers,
Wol
