I'm using ext4 for my file system.  Could the file system make a
difference if you use something else?  Your root and /home is getting a
little full.  o_O 

I didn't put anything OS related on LVM this time.  With a 1TB stick, I
figured I could make everything big enough that I shouldn't ever run out
of space.  I'd be more likely to either wear out the stick and have to
replace it or this rig will become outdated and be replaced.  I even
made /boot large.  I could put Knoppix on there if I wanted. 

Speaking of, I have /usr on the same partition as / this time around. 
Do I need a init thingy still or can I ditch that thing?  I do have /var
on a separate partition, if that matters.

:-)  :-) 

P. S.  I just ran the update command for your checksum script.  Another
torrent finished and I added a video file.
