A quick overview (the code reflects this): * Documentation changed to reflect fsck_ffs instead of fsck * Simply acts on a single filesystem, doesn't try to do any multiple filesystem magic - this is done by the fsck wrappers now And then specific to fsck_ffs: * link to /sbin/fsck_4.2bsd and /sbin/fsck_ufs. This is because right now the filesystem is of type ufs not ffs, and that during autodetection the labeltype rather than the VFS type is used - this is because when doing an autodetection of filesystem type in the fsck wrapper program, it does not have any link between label type (4.2bsd, vinum, etc) and VFS string. Note that this shouldn't break a build since the required buildworld Makefile magic and import of the fsck wrapper code into src/sbin/fsck/ will happen in a seperate commit.

a reliable environment for file storage on disk.
If an inconsistency is discovered,
corrective action must be taken.
