[CALUG] NIC gone missing with Ubuntu 11.10

[Eric K. Dickinson]

I went from 11.04 to 11.10 so it may not seem to be
a down rev thing.

Logical Volume manager and multiple filesystems are
a good thing. I just did not format my home directory
or my FS where I keep a copy of all my packages that
I install.(/usr/local)

Made the whole "Install" thing easier.
