The rated MTBF of my specific drive is 2 million hours. If I still
know my math, that's some 228 years
Which is meaningless. The life expectency of a drive is closer to the
length of the warranty period. Warranties are decided based upon
projected return rates. The manufacturers w

apt-get update hangs at
Setting up xulrunner-1.9.1
I can kill this, but then I can't finish the update because it says that
dpkg was interrupted. Trying to let dpkg repair with
sudo dpkg --configure -a
hangs setting up xulrunner so I'm stuck.
Any ideas?
