[PATCH] Bring up networking early enough for syslog= param (#470513)

[David Cantrell <dcantrell@xxxxxxxxxx>]

If a user boots from boot.iso and specifies syslog=HOST, we need
to send them through the network configuration steps in loader so
that networking is available by the time anaconda starts.
