This might be getting a bit off-topic, but I thought people might like
an explanation of what this fix does, so I'll annotate.

Single user mode means that the bare minimum of the system is started
up.  Useful mostly for fixing things.

fsck is a command that does a File System ChecK, and the -y tells it
to fix things (i.e. it automatically answers "yes" to every question
it would ask if you didn't use the "-y.")  This fixes things that get
messed up on the disk when a machine crashes.

mount is the command for mounting disks, so that you can access them.
The "root," or "/" directory, was already mounted- but it was mounted
"read-only" for the initial checks, so no files can be created or
changed.  The "u" tells the mount command to just change the kind of
mount on an already mounted drive to the "w," which means you can now
create, delete, or modify files on it.  (The root directory is the top
directory, like the ":" of MacOS 9).

cd is Change Directory, and this changes to the directory (folder)
/var/db/.

>   rm .AppleSetupDone

rm is ReMove, and this removes a file .AppleSetupDone in the /var/db/
directory.   The . at the begining of the file name means that it
won't show up in most directory listings.  "ls -a" will show it (or it
would, before it was removed).  I'm guessing that the system will look
for this file at startup, and start the Apple setup utility if it
can't find it.

>   cd netinfo

Changes into the directory /var/db/netinfo

>   mv local.nidb local.nidb.bak

mv is short for MoVe-  it renames files, and can put them into
different directories.  This takes the /var/db/netinfo/local.nidb file
and renames it to /var/db/netinfo/local.nidb.bak- the .bak is a
traditional way of saying that this file is a backup.  The local.nidb
is a NetInfo database, which is where all the stuff the system needs
to know about itself is stored- stuff like its name, I believe.

>   exit

Exits the single user mode command line "shell," so it can continue
with booting.
