Why not chdir into the root of container right when
the root filesystem is (bind-)mounted, and let all
mount entries to be relative to the container root?

Even more, to warn if lxc.mount[.entry] contains
absolute path for the destination directory (or a
variation of this, absolute and does not start with
container root mount point)?

This way, all mounts will look much more sane, and
it will be much easier to move/clone containers -
by changing only lxc.rootfs.

I do it this way locally since the beginning, by
chdir'ing to the proper directory (rootfs) before
running lxc-start (in a startup script), but this
is now broken in 0.7.3 which bind-mounts rootfs
somewhere in /usr/lib/lxc.

Add support for `dirsync' mount option. MS_DIRSYNC is on of the
mount(2) mountflags so don't send it as extra mount option to avoid:

 	lxc-start: Invalid argument - failed to mount ...

We don't want to drop the capabilities when we are root because that

This commit adds an configuration option to specify a script to be
executed after creating and configuring the network used by the
container. The following arguments are passed to the script:

	* container name
	* config section name (net)

Additional arguments depend on the config section employing a
script hook; the following are used by the network system:

	* execution context (up)
	* network type (empty/veth/macvlan/phys)

Depending on the network type, other arguments may be passed:

veth/macvlan/phys:
	* (host-sided) device name

In the case we use an image for rootfs, if we need to do extra mount
from the host to the rootfs, we have to specify the place where the
image is mounted. This value is configured by the user with the
lxc.rootfs.mount otherwise defaulting to @LXCROOTFSMOUNT@. Let's 
export this variable to pkg-config, so the user can use it to build
a correct path to the rootfs.

When a container is installed with 32bits binaries while we are
running on a 64bits host, inside the container we are seen as
64bits arch. That leads to some problems for the package updates
because the scripts will download 64bits packages instead of 32bits.

This patch defines a configuration variable to set the architecture
of the container.

lxc.arch = i686 | x86 | x86_64 | amd64
