3 * fsck --- A generic, parallelizing front-end for the fsck program.
4 * It will automatically try to run fsck programs in parallel if the
5 * devices are on separate spindles. It is based on the same ideas as
6 * the generic front end for fsck by David Engel and Fred van Kempen,
7 * but it has been completely rewritten from scratch to support
10 * Written by Theodore Ts'o, <tytso@mit.edu>
12 * Miquel van Smoorenburg (miquels@drinkel.ow.org) 20-Oct-1994:
13 * o Changed -t fstype to behave like with mount when -A (all file
14 * systems) or -M (like mount) is specified.
15 * o fsck looks if it can find the fsck.type program to decide
16 * if it should ignore the fs type. This way more fsck programs
17 * can be added without changing this front-end.
18 * o -R flag skip root file system.

30 * If filesystem cannot be determined, we will execute
31 * "fsck.auto". Currently this also happens if you specify
32 * UUID=xxx or LABEL=xxx as an object to check.
33 * Detection code for that is also probably has to be in fsck.auto.
35 * In other words, this is _really_ is just a driver program which
36 * spawns actual fsck.something for each filesystem to check.
37 * It doesn't guess filesystem types from on-disk format.
