[lxc-users] Is calling external mount-binding scripts supported with Ubuntu's upstart scripts?

You can use 'lxc.hook.pre-mount' (see lxc.conf or lxc.container.conf
manpage for this), which is called in the container's mounts
namespace, but without the container rootfs set up.  You can
also use 'lxc.hook.mount', which is called later, after the
rootfs has been setup, but before it has done pivot_root, so you
stil have the host / available.
