Removing files with find, and LVM snapshots

Take an LVM snapshot using a loopback device

Code:

I started my computer and noticed the little triangle thingy (it's not technically a triangle, the top side is bowed out, more of an arc than a straight line) in the upper right hand corner of my computer screen didn't have any lines in it.
