It probably was messed up, although I *thought* that I had the stock 
fedora.us apt.conf file with the single modification of having 
"--excludedocs" as an install option. Maybe I made some other change.

I did, but it failed with the problem of grubby not finding a template,
which had been wiped by the failed kernel upgrade. Anyway, I'm really
happy with the reinstallation, I've got lots of room to mess around with
now.

Maybe. I used AIX LVM years ago on an RS6000, it is nice. On this 
particular machine I'm at too many limits to make it worthwhile (no more 
power allowed). On a new box with lotsa room for expansion, sure.
