I added the third line to /etc/fstab.
proc /proc proc defaults 0 0 none /dev/pts devpts rw 0 0 tmpfs /dev/shm tmpfs defaults,noexec,nosuid 0 0
Then I run
mount -a to mount it. The problem is that when I reboot, I again have to run
mount -a. Is there another file I should be editing to make these changes permanent, or have
mount -a run automatically?
In case it matter, I'm running on a VPS on MediaTemple.
