A little background... I had been looking into the possibility of placing /tmp on a tmpfs instead of the dedicated partition I had been using. As CentOS 5.9 has come out, I decided to reboot a server in order to utilize the newest kernel. Upon reboot, I noticed that my /etc/fstab had been changed, and that /tmp was now mounted on /usr/tmpDSK instead of the dedicated partition. I don't remember having done anything what would have caused this... but I decided to take this as an opportunity to mount /tmp to on a tmpfs. I also decided I'd like /var/tmp mounted on the original dedicated /tmp partition. I commented out the associated lines in /etc/fstab, added the desired mounts for /tmp and /var/tmp, and rebooted the server. Upon reboot, /tmp was mounted correctly on tmpfs, but my setting for /var/tmp was overruled, and was mounted on /tmp. Is there a reason I'm being overruled? How do I prevent this?
