Issue with rc.d/netif script when modifying NIC state after boot

[Garrett Cooper]

optimus# /etc/rc.d/netif start
/etc/rc.d/netif: DEBUG: run_rc_command: doit: network_start
/etc/rc.d/netif: DEBUG: Cloned:
/etc/rc.d/netif: DEBUG: checkyesno: synchronous_dhclient is set to NO.
Starting Network: lo0 msk0.
ifconfig: msk0: bad value # <--- this didn't happen before (why is
ifconfig lo0 msk0 trying to be run? shouldn't this be a for looped
deal?)...
/etc/rc.d/netif: DEBUG: The following interfaces were not configured:
/etc/rc.d/ipfilter: DEBUG: checkyesno: ipfilter_enable is set to NO.

I've posted the contents of a set -x operation over the script, here:
