# this script makes sure your .mozilla folder is in tmpfs and constantly syncs it
# with a folder on your hdd so you won't lose anything :)
# for more details on how it works visit my blog in the link above.
#
# for this to have any meaning, the MOZTMPFS folder must be on tmpfs
# i.e. to make /var/tmp a tmpfs folder, add the following in /etc/fstab
# tmpfs      		/var/tmp	tmpfs  size=768M,mode=0777         0 0

# don't forget to mount the first time!
