tmpfs /tmp tmpfs defaults,nosuid,nodev,mode=1777,size=1G
In squeeze, edit /etc/default/tmpfs:
SHM_SIZE=6G
TMPFS_SIZE=1G
RUN_SIZE=10M
LOCK_SIZE=1M
RW_SIZE=10M
(adjust to your needs).

tmpfs does not support security labels in 2.6.32, which limits SELINUX
heavily. There is no workaround (unless Debian backported the support to
2.6.32, I didn't check). Switch to per-user TMP directories is recommended.
