It was because emerge told me it needed it for some reason.  It is very
rare that I just put something in package.use on my own.  On the rare
times I have done it, it is on a package that I use and I need to enable
something but don't want to enable it globally or only that one package
has that USE flag.  A couple examples, gimp, nut, gtkam is a few that I
have in there because of some option I need to enable/disable.

I don't have / on lvm.  /boot and / are on regular partitions. 
Everything else, /usr, /var and /home, are on lvm.  Keep in mind, I was
trying to avoid that init thingy. 

I mentioned genkernel because Mike mentioned it.  I tried it ages ago
and never got a kernel that would boot.  I don't even have it installed
here.  I started doing them by hand and have been pretty good at it ever
since.  Odd I know.
