When I do those steps in a container, just typing 'mount' no longer shows /cpu mounted. (If I had to guess at something, I'd say you have /etc/mtab linked to /proc/mounts, and something with that is going wrong, but it could be not that) Check /proc/self/mounts before and after each step, compare to /etc/mtab. And try doing mount -n and umount -n. -serge _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
