| 2 | * pfsck --- A generic, parallelizing front-end for the fsck program. |
| 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. |

Mike Frysinger | 51a43b4 | 2005-09-24 07:11:16 +0000 | [diff] [blame] | 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. |
