41e32d9f | 2 | * fsck --- A generic, parallelizing front-end for the fsck program. |
607c2a72 KZ |
3 | * It will automatically try to run fsck programs in parallel if the |
4 | * devices are on separate spindles. It is based on the same ideas as | |
5 | * the generic front end for fsck by David Engel and Fred van Kempen, | |
6 | * but it has been completely rewritten from scratch to support | |
7 | * parallel execution. | |
8 | * | |
9 | * Written by Theodore Ts'o, <tytso@mit.edu> | |
10 | * | |
11 | * Miquel van Smoorenburg (miquels@drinkel.ow.org) 20-Oct-1994: | |
12 | * o Changed -t fstype to behave like with mount when -A (all file | |
13 | * systems) or -M (like mount) is specified. | |
14 | * o fsck looks if it can find the fsck.type program to decide | |
15 | * if it should ignore the fs type. This way more fsck programs | |
16 | * can be added without changing this front-end. | |
17 | * o -R flag skip root file system. | |
