It should boot up just fine. You can test things by dropping to run
level 1 (telinit 1), and running "mount /dev/sdb1 /usr", and then
going back to run level 5. If you did everything correctly, you
should have the GUI login, and everything should work. I am not 100%
sure that --preserve=all will copy the selinux context attributes.
If it doesn't, you will need to relabel the /usr tree.

You may want to rename /usr to something else, and create a new /usr
to serve as the mount point. Once you are sure everything is
working, you can delete the old /usr tree to regain that space. If
you use the current /usr as your mount point, it will hide all the
existing files.
