many modern distros delete /tmp on reboot and/or play
games with namespaces to isolate different users' /tmp spaces.

So if the machine crashes during a rebuild, you may lose that backup
file, depending on the distro.  OK. 

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 ...
