[1765] | 3 | * fsck --- A generic, parallelizing front-end for the fsck program.
|
---|
[821] | 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
|
---|
| 8 | * parallel execution.

|
---|
| 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.
