Because it's a quite classic thing to use a bridge to bind a container on the host's physical interface in order to provide it some network access, although there's other solutons. > I can only find usage of the 'brctl' command in: > 1: ./templates/lxc-gentoo.in > 2: ./src/tests/lxc-test-usernic.in > > The second one seems to only conditionally be installed on ubuntu > according to src/tests/Makefile.am, so not relevant.

That said, you're right, one could use iproute2, as ip link show type bridge works perfectly fine to list bridges, and ip link is actually able to manage bridges as well as brctl. That said, I'm not sure at all that removing any recommendation to bridge-utils is a fine idea. The number of people not aware of the fact that ip link does the same job is quite high. I'm open to discussion on it, of course. I added iproute2 as a Recommend for lxc 3.0.2-1~exp+3 (3.0.2-1~exp+2 is in experimental for now, +3 will follow at some point), but without removing bridge-utils yet. -- Pierre-Elliott Bécue GPG: 9AE0 4D98 6400 E3B6 7528 F493 0D44 2664 1949 74E2 It's far easier to fight for one's principles than to live up to them.
