This is simply a warning message indicating that the filesystem was
not properly unmounted last time it was used, and so might - *might* -
need to be checked over by e2fsck.
The problem is that there is currently no way to unmount the root
filesystem. So, there is no way to cleanly shut down the root
partition. If you use the proper reboot / halt commands, then all of
the other partitions will be properly unmounted, and you won't get
any valid warnings from them.
As long as you are careful not to shutdown or reboot without syncing
(which gets done automatically by the standard halt/reboot commands),
then it is safe to ignore this message.
