- * pfsck --- 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.
- *
- * Written by Theodore Ts'o, <tytso@mit.edu>
- *
- * 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.
