[systemd-devel] unable to create bridge name "default"

[William Tu]

Hi,
I'm not sure if this is caused by systemd-udev, apology if it's not
the right place. When doing
# brctl addbr default
add bridge failed: Invalid argument
or
# ip link add name default type bridge

Debugging with
# systemd-udev --debug

I think the bridge "default" is created successfully first, then
somehow get remove immediately after it gets created. Is this related
to systemd disallow using "default" as device name? Thanks
