Re: Shutdown issues

[Shaun Savage <savages@pcez.com>]

There are two ways to fix this problem,
Easy:
	just toggle out of enforcing mode sometime during shutdown.
Hard:
	 move the shutdown of the syslog to later and try to capture the 
messages, then fix it.  Or you can via sysadm role shut down just the 
services.  The problem here is sysadm_t != initrc_t.  you have to do a 
runs as.  Also even with enforcing off you get messages.
