It is using /dev/shm per the docs at http://www.mimedefang.org/node/20 which
I think translates to tmpfs if I'm interpreting the df correctly.
So ... should I not specify a size?
Here is the recommended command from the documentation:
/bin/mount -t tmpfs -o size=500m,mode=0700,uid=defang,gid=defang /dev/shm
Here's what I'm using (100m)
/bin/mount -t tmpfs -o size=100m,mode=0700,uid=defang,gid=defang /dev/shm
Here's my df output:
Filesystem 1K-blocks Used Available Use% Mounted on
72791328 10940064 58153600 16% /
/dev/sda1 198337 22590 165507 13% /boot
tmpfs 986408 0 986408 0% /dev/shm
/dev/shm 102400 3368 99032 4%

If you are using a tmpfs ramdisk you will not waste memory. The more
data is written the more of your capacity will be used and memory will
be added dynamically (and freed when capacity not used anymore).
Make sure you have the swap to back up incase of memory starvation (ie
so your tmp will not wake up the OOM monster).
Usualy for every 1Mb of tmpfs I add I add 1Mb of swap, nearly never gets
used but diskspace is cheaper than RAM and at high memory usage (the
tmpfs will get swapped out usualy) the "ramdisk" performs slow but will
not crash ur system.
See http://en.wikipedia.org/wiki/Tmpfs for more info on Tmpfs, stay away
from the traditional ramdisks (just eating up ram and all, with no swap
Hope it helps
