One thing that's not
safe is leaving your computer
halfway through an
apt-get upgrade which gets
interrupted by an
error or for some other
reason. I did this, and
X started okay, but once it was into
GNOME the computer started sending all kinds of random
keystrokes to the
gnome-terminal I had running. I tried to move my
mouse to close it, but the mouse was all
fucked up and the
pointer jumped around and sent random
clicks. It managed to open up
mutt and do
random things to
e-mail messages as I tried
ctrl-alt-backspace, which didn't work. And I've got a
stupid keyboard which goes
catatonic when I press
Alt-
SysRq. I had no choice but to hit the
power button.
Finishing the apt-get upgrade solved everything, but this goes down as the most impressive complete crash of Linux I've seen.
