SELinux revisited

Greetings;
Running 2.6.23 here, on a AMD XP-2800, gig of ram, lots of drive.
I thought maybe I should give selinux another chance here. So I removed the
selinux=0 in my grub.conf, and edited its .conf file in /etc/sysconfig to set
it for permissive.
On the reboot, the relabel wasn't done, so I looked around and reset a
fresh /.autorelabel file and rebooted again. It was already present however.
This time it did a very short autorelabel, maybe 2 screens full and was done
in just a couple of seconds, at which point it went into yet another reboot
cycle making me think it was stuck in a loop or something.
But the next reboot then had auditd advise me there was an error in line 16
of /etc/audit/auditd.rules.

# The rules are simply the parameters that would be passed

Not having any idea if it counts lines by lf's, or if it ignores commented
lines in its line count, so I have NDI what its fussing about. FWIW, I am
not running a dhcp network, just a server so my lappy can log in. Everything
else is in my /etc/hosts file.
Watching the audit.log with a tail, res=success seems to be a 100% answer so
far.
1. The last time I watched an autorelabel, it took about 10 minutes, why was
it done this time in <2 secs?
2. What can I do about the rules error?
