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.
