I haven't closely followed this thread, but I'd guess that his
root is mnt_shared. Can confirm by doing 'grep shared /proc/self/mountinfo'
Private mount namespace doesn't stop that. So if it doesn't already, lxc
should probably (optionally?) do a
mount --make-rslave $lxc_root
after creating it's tmpfs rootfs or pivot_rooting.
(Or, I could be completely wrong :)
