[lxc-devel] [PATCH] lxc-busybox: check when bind-mounting host libdirs

[Bogdan Purcareata]

The patch changes the busybox template behavior to automatically
mount /lib and /usr/lib. In case one of these folders does not exist,
starting the container will fail. Also, if there are other lib entries
on the host - e.g. /usr/lib64 -  mount them as well.
