I think I now see the issue... I only tried net_interfaces="vlan0" because
after a reboot, vlan0 wasn't created.

In /etc/rc.d/network, I see:

                for cloner in $(/sbin/ifconfig -C); do
                        for int in /etc/ifconfig.${cloner}[0-9]*; do
                                [ ! -f $int ] && break
                                tmp="$tmp ${int##*.}"
                        done

ifconfig -C certainly returns vlan, but then it looks as though I need
the /etc/ifconfig.vlan0 file rather than being able to try the
fancy variable (c.f., original message...).

Might need a -a -n eval \$ifconfig_$cloner or somesuch...
