I'm not sure what would cause this, but it can happen if the init scripts
try to close down the root partition before all the processes have died.
If you have a process that won't die, this can happen. But it doesn't
really hurt anything, since the files are in a pretty clean state anyway.

This just means exactly what it says. Every so often, a filesystem gets
checked, whether it needs it or not.

Tells you how many of your files are not contiguous on the disk. 4.3% is
a very good percentage.

A defrag exists for Linux but you don't need to use it. The Linux kernel
keeps the filesystems pretty defragmented as it is. If you split /usr and
/home off on separate partitions, it stays even more defragmented.

This usually means that a device, probably a network card, had a problem
with the configuration. If everything seems to be working correctly,
ignore it.
