I'm temporarily running selinux in permissive mode and seeing a few
security gripes in /var/log/messages. I assume this means that if I
were to turn selinux back on fully I'd see some aspect of postfix
operation start to fail.

I've run restorecon as such to fix things up, but
/etc/postfix/prng_exch seems to un-set the correct settings
periodically.
restorecon -r -n /etc/postfix
Is this operator error, or do I just need to cool my heals a bit till
someone fixes the internals of postfix to deal with the selinux
permissions better?
