and the default route is attempted before the vlan interface is all the =

the rc.conf syntax OK.

Yes running it manually after the system is booted works, though I see =
two errors that may indicate something.  See below.

I edited /etc/netstart and /etc/rc.d/netif and 'set -x' in both.  Those =
two errors are coming from netif.  I'm still looking into what it does =
not like.
