There is a trick to this if you don't want to unmount stuff...
You can use a bind mount to access the filesystem without recursing into
the other filesystem.

Do: mount -o bind / /mnt
Then your /mnt will be exactly like / except the other mounted
filesystems will not be there so you can access the mount point
directories as if nothing was mounted in them.
