/tmp shouldn't really hold any data that are meant to survive a panic or
power failure anyway. On most of my systems I have /tmp mounted on an
mfs. (Which is abviously completely lost during reboot / power

I sometimes thought that on other systems mounting /tmp asynchronously
might be good idea, but it might prevent an automatic reboot in case
of unexpected inconsistency. Is it advisable or even possible in a
simple manner to have /tmp fsck'd with the -y flag automatically?
