I remember a post of Kirk McKusick forwarded by someone to one of the
lists that mentioned why this is necessary.  Some of the filesystem
metadata and/or superblock information is kept in different places now.
The mount won't fail if you try it without having run fsck before, but
disk usage reporting tools like du and df will print wrong information
until you *do* run the fsck.
