What I don't know is what would happen if you them try to mount /usr. As I can not see any valid reason to do it, I have never tested it. What I suspect would happen if that you would no longer be able to access anything that was on /usr/tomcat, but you might get an error message when trying to mount /usr instead. The only use I can see for doing it is if you want to open some files on /usr/tomcat, and then hide the /mnt/tomcat file system. It would be one way to hide a rootkit, or backdoor code.
