I don't know  about building packages but if you  want to unleash "git
filter-branch" on a reasonably sized repository then you *really* want
your  temporary directory  to be  in memory.   (The command  accepts a
custom temporary directory which is  convenient if eg.  /dev/shm is in
memory but /tmp is not.)

Also, many audio/multimedia  HOWTOs advise you to have  /tmp in memory
but I  haven't used such  software in enough  anger to see  how useful
that is.
