* fsck --- A generic, parallelizing front-end for the fsck program.
|
|
|
|
* It will automatically try to run fsck programs in parallel if the
|
|
|
|
* devices are on separate spindles. It is based on the same ideas as
|
|
|
|
* the generic front end for fsck by David Engel and Fred van Kempen,
|
|
|
|
* but it has been completely rewritten from scratch to support
|
|
|
|
* parallel execution.

|
* Miquel van Smoorenburg (miquels@drinkel.ow.org) 20-Oct-1994:
|
|
|
|
* o Changed -t fstype to behave like with mount when -A (all file
|
|
|
|
* systems) or -M (like mount) is specified.
|
|
|
|
* o fsck looks if it can find the fsck.type program to decide
|
|
|
|
* if it should ignore the fs type. This way more fsck programs
|
|
|
|
* can be added without changing this front-end.
|
|
|
|
* o -R flag skip root file system.
