RHEL ES 4.7: chmod settings reset on reboot

This is probably a newbie problem, so forgive me, but when I do this:
chmod o+rw /dev/nst0

It resets back to what it was upon reboot. How do I get this change to stick?

I tried searching the forums and Google, but I haven't found an answer.

AFAIK, you can't change device permissions and expect it to survive a reboot without some help -- e.g. using udev.

Add the following line to /etc/udev/rules.d/50-udev.rules
KERNEL="nst0", MODE="0666"
After the next reboot, the permissions should be set as you want them.

(I have not tested this. Be sure to backup your config file first, and be prepared to troubleshoot.)
