PATCH 1/1 init-live.sh: avoid duplicate mount points for the same filesystem
From: Chen Qi <[email protected]>
A live system had duplicate mount points for the same filesystem in the output of 'mount' command. That was because we didn't handle the temporary mounts properly before switch_root.
This patch fixes this problem by moving the mount points of some filesystems to the corresponding directories in the real root filesystem.
