I am trying to experiment with mount namespace in Ubuntu. So far I can create an empty mount namespace using the following:
# mkdir test
# unshare --mount
# mount none test -t tmpfs
# cd test
# pivot_root . .
# cd / <--- test becomes /
When I check a LXC
Ubuntu container, the mount
command displays the following:
Since the mount namespace initially gets a copy of the mount points, I presume the /dev/sda1
inside the container is the global /dev/sda1
(because there is no /dev/sda1
inside the container once it is started), and yet the contents of the /
inside the container correspond to its rootfs. Can someone familiar with LXC please explain what mount operations does LXC do before it does its pivot_root
inside the container ?
