well, I totally screwed up my Debian Lenny install last night. I was 
fighting an application error, made some bad choices, and ended up with 
a non-useable system. X wouldn't work & I could not get apt/aptitude to 
do anything worthwhile.
SO, 9pm last night I started the squeeze upgrade process. just about 
finished it last night ( gnome login worked, but KDE was not to be 
found). That was about 12:30am..
6am I was back at it.. oops, ran out of "/" file space, that sucks.. 
removed a bunch of useless apps.. got some space back. Installed 
trinity.. fixed a few squeeze upgrade issue, and about noon today I had 
my system back.  My wife's desktop looks just like it did yesterday, 
except it says "trinity" on the left hand side:) I doubt she will 
notice. Her kmail is up & running, as is my gnome login.
