Description of problem:
The VNC locks are not being deleted during system startup 
(/etc/rc.d/rc.sysinit).  After a crash, vnc will not load any more until the 
locks are manually deleted.  The locks should be removed at startup because no 
VNC session should be running yet.  Usage of /etc/sysconfig/vncservers is 
difficult without removal of the VNC locks.  I suggest removal of the VNC locks 
be placed next to removal of X locks in rc.sysinit.

# Delete X locks
rm -f /tmp/.X*-lock

# Delete VNC locks
rm -rf /tmp/.X*-unix

How reproducible:
Always

Steps to Reproduce:
Reproducible either using /etc/sysconfig/vncservers or just running vncserver 
manually.
1. Set up an entry in /etc/sysconfig/vncservers: VNCSERVERS="1:root"
2. Reboot, notice that a vncserver will be started for DISPLAY #1.
3. Hard Power Off or kill the vncserver so that it does not get a chance to 
remove its vnc lock in /tmp (kill -9 [pid of vncserver]).
4. Boot the system.

	

Actual Results:  The VNC lock still exists and will not allow vncserver to 
start.  The VNC lock must be removed manually before a vncserver session can be 
started on that display again.

Expected Results:  The VNC lock should have been deleted during bootup so 
that /etc/rc.d/init.d/vncserver could have started the vncserver session.
