Two possibilities. First check whether the mount exists in /proc/self/mounts. If not, then (a) this isn't why you can't destroy the container, and (b) the mount was inappropriately recorded in /etc/mtab, meaning the template should use mount -n. Second, if your rootfs is MS_SHARED, that could cause the rootfs mount done from the container init to be propagated to the host. But lxc should detect at least if '/' is shared and work around that. If however you have /var/lib/lxc MS_SHARED and not /, then lxc probably will not work around it. -serge ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
