I am migrating a samba server from FC3 to FC5. I did a fresh install

have run into an SELINUX policy issue. I have no problem logging on as
root and typing in rsync --daemon, but when I insert the same line at the
end of /etc/rc.d/rc.local and reboot, then /var/log/messages shows the
following (with other stuff edited out).

The rsync policy appears to assume that rsyncd will run from xinetd
rather than using daemon mode. Not allowing rsync_t to bind to
rsync_port_t does look like a bit of an omission...
