This is processed by the following code in
/etc/network/if-pre-up.d/bridge:
----------------
if [ "$IF_BRIDGE_WAITPORT" ]
then
set x $IF_BRIDGE_WAITPORT &&
shift &&
WAIT="$1" &&
shift &&
WAITPORT="$@" &&
if [ -z "$WAITPORT" ];then WAITPORT="$IF_BRIDGE_PORTS";fi &&
STARTTIME=$(date +%s) &&
NOTFOUND="true" &&
/bin/echo -e "\nWaiting for a max of $WAIT seconds for $WAITPORT to become
available." &&
while [ "$(($(date +%s)-$STARTTIME))" -le "$WAIT" ] && [ -n "$NOTFOUND" ]
do
NOTFOUND=""
for i in $WAITPORT
do
if ! grep -q "^[\ ]*$i:.*$" /proc/net/dev;then NOTFOUND="true";fi
done
if [ -n "$NOTFOUND" ];then sleep 1;fi
done
fi
----------------
This means a
bridge_waitport 0
has at best no effect (all configured ports already available) and at
worst, it will cause 1s wait for them.
