If /tmp is in RAM, it Here's my 0.02 Euro (feel free to correct errors). /tmp in RAM surely refers to Solaris. On Solaris, /tmp is actually implemented as pages taken from RAM+swap - this is no problem since it is supposed to be erased on reboot. Unless Solaris is very stupid, there is actually no duplication between the filesystem and the cache, since the filesystem is actually in the cache! /var/tmp is a normal disk-based filesystem.
