If you build without cgmanager, and your system has the cgroups individually mounted under /sys/fs/cgroup, then cgfsng will be automatically used. > > > Can I help in any way? > > > > If you were feeling bored and/or industrious, you could > > grab the lxc git tree and git bisect to the commit that > > breaks it :) I'm 99% sure it'll point to the commit that > > introduces run_command(), but actually it's possible that > > I am actually wrong about that, so confirmation would be > > useful. > > > > Or instead of a bisect, you could just revert ea3a694fe > > in the 2.0.9 tree and see if that fixes it.

The 'not much used any more' isn't referring to unprivileged containers, but to use cgmanager, which is deprecated (until we decide we need it again :) -serge _______________________________________________ lxc-users mailing list [email protected] http://lists.linuxcontainers.org/listinfo/lxc-users
