Or bind mount root to somewhere else:
mount -o bind / /new
/new then contains all of / , but without the filesystems mounted at root.
It also has has the original /dev with its necessary entries console and
null, but without the stuff udev added.
It also takes care of /tmp. Its contents are unimportant, but the
permissions of the directory itself matter, the sticky bit needs to be set.
