Use /var/tmp for the cached appliance (for FHS compliance).
The FHS advises large files not to be stored in the root
filesystem[1], and that /var/tmp is persistent across reboots[2]
(whereas /tmp is possibly not[3]).
Therefore we should store the large cached supermin appliance in
/var/tmp instead of /tmp. /tmp is still used for all other temporary
files and directories.
In either case you can override this by setting $TMPDIR.
