But having /tmp as a tmpfs *does* make a difference

Thanks for the tip on this one - I just changed mine (/tmp was on /) and,
man, did it make a difference to how kde 4 runs?!!

My brain isn't connecting with what to actually do in fstab to accomplish
this. Right now I have:

LABEL=07tmp /tmp /ext2 noatime,noacl 1 2

What would I do instead?


Try it out first with:

mount -t tmpfs /tmp [-o size=<value>]

Then if you want to make it permanent add the following to /etc/fstab:

none /tmp tmpfs size=<VALUE> 0 0

Size is optional - it defaults to 50% of RAM. It accepts either a value in
bytes (e.g. 200m for 200MB) or a % (of RAM) - mine is set to 25% as a starting
point. BTW, size is the *limit* - it will not grow past that (but it will only
use what it needs otherwise).
