[Lxc-users] lxc.mount.entry denied mount permission for -t ext4?

When I added an ext4 lxc.mount.entry to a working Ubuntu 10.04
container, lxc-start stopped working.  Please help me understand why.
A partial strace is below, and a copy of proud.conf.

At first I thought that lxc-start wasn't allowed to mount it because
SYS_ADMIN was dropped -- but if that's so, why is it allowed to mount
-obind?  I checked, and -obind is NOT allowed inside the container (when
booting it without the ext4 lxc.mount.entry).
