From Bugzilla Helper:

Any user may prevent "/etc/rc.d/init.d/named restart" from working properly.

Reproducible: Always
Steps to Reproduce:
1. execute /usr/sbin/named as an arbitary local user
2. as root, execute /etc/rc.d/init.d/named stop
3. as root, execute /etc/rc.d/init.d/named start


	

Actual Results:  named start fails (tried with bind-8.2.3-0.6.x)


Expected Results:  named should have started correctly, and user process
should be ignored, or killed.

Executing execute /etc/rc.d/init.d/named stop twice will work around this
problem.

The current version of bind can't be run by an arbitrary user.
