By default tmpfs allocates half of the physical ram. That value can be
changed specifying size=size when mounting. For example on a machine
with 2GB of ram by default it would use 1GB. If we wanted to make it
512MB mount it as follows:

# mount -t tmpfs -o size=512m /dev/shm /tmp_shm

You can on Red Hat variants change /etc/fstab to mount /tmp on ram


none	/dev/shm	/tmpfs	defaults	0 0


None	/tmp	/tmpfs	size=512m	0 0

How does one modify the size of a tmpfs partition? I thought it just 
took whatever RAM was available.
