I don't think so
the initial loop is not activating bridge and vlan:
if [ "$TYPE" = "Bridge" ]; then
bridgeinterfaces="$bridgeinterfaces $i"
continue
fi
if [ "${DEVICE%%.*}" != "$DEVICE" ] ; then
vlaninterfaces="$vlaninterfaces $i"
continue
fi
Then later:
for i in $vlaninterfaces $bridgeinterfaces ...
<snip a few lines>
action $"Bringing up interface $i: " ./ifup $i boot
So, it should be bringing up your vlan interfaces before the bridges
do you have
TYPE=Bridge
in your bridge ifcfg file?
