I was surprised by this because whether you set up a bridge manually
or, on RHEL, via ifcfg files (or on Gentoo via net and net.* files),
you have to define and bring up the bridge components.
A "man -k bridge" reveals "bridge-utils-interfaces" and "man
bridge-utils-interfaces" explains:
<======

bridge_ports interface specification

You should not put any lines to configure the interfaces that
will be used by the bridge, as this will be setup automatically
by the scripts when bringing the bridge up.

So I've been mimicking the RHEL way on Debian and Ubuntu and setting
up bridges in "/etc/network/interfaces" incorrectly. :(

LOL. Good luck but it should be OK. (Famous last words!)
