bridge-utils all-regex does not capture network devices

[rainer z]

from bridge-utils-interfaces(5)

bridge-ports
 ...
 Specifying "all" is short for "regex eth.* em.* p[0-9].* noregex" and will get all the ethX and
 biosdevname-format (emX and pX) interfaces added to the bridge.

This will NOT capture device names like enp* and network init will hang.

i literally installed the os and the package, threw this in /etc/network/interfaces :

  auto br0
  iface br0 inet dhcp
        bridge_ports all

and rebooted.

Then spent half an hour figuring this out.

Hi! Thanks for looking into this and determining what was going on.

Based on the documentation I agree that it is not capturing enp* network devices. However, as the man page says you can add a regex if you want to capture other types of interfaces:

bridge_ports regex enp.*

If you desire to change the behavior of the 'all' wildcard, then I would suggest filing an upstream bug report to change this behavior. I will mark this as a wishlist bug.
