File system corruption?
What file system do you have? If it is something with a journal (ext4,
for example) I would be surprised. If it is something experimental or
less reliable (btfs, reiserfs?) then I wouldn't be surprised.
All file systems can lose data if you interrupt them while updating the
file system, but some are more resiliant than others. I tend to prefer
the good old ext3 or ext4 standby over flashier, faster but less
resiliant newer file systems, and older, unjournaled file systems like
ext2.
Have a look inside /lost+found (assuming /usr/bin is in the / partition)
and see if there's anything there. You may find all your X files, and
more, given generic names. Or you may find nothing at all.
