FreeBSD Issues

Okay! Here we go.

I've fixed the following so far...

[x] - A problem in spacing for the FreeBSD logo
[x] - Disk related errors for *BSD. It was showing up as 438G / 11G (3182%) on mine. Grabbing the first line of df is unreliable. Also, there is not total shown in *BSD df without -c AND it appears at the end. So, I've added that flag and converted head -1 to tail -1.

What's not done:

[ ] - Fix for memory detection. Do not rely on anything /proc related in BSD. It doesn't exist. /proc is mostly a purely linux thing. If you insist on relying on /proc, you're going to have to advise to BSD users to load the linux-compat kernel module that enables /proc. The original code in sF is quite extensive for *BSD mem detection. You may want to take a look at it.
[ ] - Package detection is broken in 10.0-CURRENT, but mostly because of pkgng messing up my pkg dbs. I wouldn't worry about it too much.
