Then those people should use /var/tmp instead of /tmp.
Traditional UNIX behaviour is that contents of /var/tmp
must survive a reboot, while contents of /tmp are not
guaranteed to survive a reboot (and in fact, /tmp might
be cleaned completely at regular time intervals via a
periodic cron job or similar). That's why vi puts its
recovery files under /var/tmp, not /tmp.
However, there are still cases where it's not desirable to
make /tmp a memory-based file system, e.g. on systems that
have little RAM and/or no swap (or NFS swap). Also, some
people argue that a UFS disk partition with softupdates (or
even async) is fast enough for most purposes to be mounted
on /tmp. (For what it's worth, I've seen systems set up in
a way to newfs the /tmp partiton on reboot.)
Therefore, I think the best solution would be to make it an
option in sysinstall: If the user doesn't create a separate
partiton for /tmp in the partition editor, ask him whether
he would like to make /tmp a memory-based file system. Or
implement a special hotkey in the partition editor for
creating a memory-based file system -- I guess this would
be the easiest way to implement it.
