Note - I messed up. This was applied upstream, but I dropped it in

be reapplied.

(sorry for the extra traffic.)
With this patch, lxc works for me both with all cgroups mounted with
ns cgroup on /cgroup, and with libcgroup mounting all cgroups
separately.
To do this, instead of looking for one cgroup called 'lxc' or
otherwise taking the first cgroup we find, we actually create a
container in every mounted cgroup fs. Right now it's done under the
root of each fs. We may want to put that under lxc, or, better yet,
make that configurable.

v3: use the rest of Daniel's cleanups
TODO: add a configurable directory name, 'lxc' by default, under which
all lxc cgroups are created (i.e. /sys/fs/cgroup/lxc)

The good news is, starting with next openSUSE release (and next SLES 11
Service Pack), patching /etc/init.d/boot won't be needed anymore for
LXC, we integrated detection of LXC (through container variable set to
lxc) in /etc/init.d/boot and /dev is no longer mounted automatically by
initscript.

Consolidate lucid, maverick, natty, and oneiric templates into one 'ubuntu'
template.
Add support for specifying architecture.
Add support for '--trim|-x' option, which removes services like the lucid
template used to. This creates smaller, faster-booting containers, but they
will not be safe with certain upgrades, like mountall or udev. When -x is
not specified for lucid or maverick container, then install lxcguest from
the ubuntu-virt ppa, since it does not exist in the official archives, and
the container is not safe to boot without lxcguest.
Add support for '--bindhome <user>' option, which will cause /home/<user>
to be bind-mounted into the container, and create the user with his
original password, shell, and group memberships in the container.

Create an lxc-clone script to clone containers. It should probably
be factored into helpers and then enhanced, in particular to convert
between LVM and non-LVM containers, create non-snapshot LVM clones,
support loopback devices, and, when stable enough, to use
overlayfs, btrfs, etc.
But this is a start.

'setns.h' is not an lxc interface.
Also, a side effect of this declaration of 'setns.h' in the lxc header
files is to be distributed in the lxc tarball. This breaks the

compile time.

lxc_cgroup_path_get currently cache the cgroup mount point plus the
container name at the same time, making every call of the function
returning the same value.
It mean that actually every call to lxc_cgroup_get with a different
container name will in fact use the same container name as used for
the primary call.
I join a patch to fix that, still doing some caching, but only caching
the cgroup moint point this time. This patch actually work for me, as
I am using the liblxc for retrieving statistics about all running
containers, using lxc_cgroup_get to retrieve every interesting values.
