573 *
574 * - If the partition is mounted (e.g. /dev/sda1 is mounted on /boot), it adds an entry
575 * to the linked list, copies to it the device name and mount point, and sets check == 1.

577 * - If the partition is part of a Volume Group that has Logical Volumes mounted, it adds
578 * an entry to the linked list for each mounted Logical Volume in that Volume Group, copying
579 * to it the device name and mount point, and sets check == 1. Note that if the Volume Group
580 * contains more than one disk, it will still add the entry even if the Logical Volume's
581 * extents are not on the dsf that was passed in to the function. For example, Volume Group
582 * VolGroup00 contains the disks /dev/sda1 and /dev/sdb1, and the Logical Volumes LogVol01,
583 * which is mounted on /var and has all of its extents on /dev/sda1, and LogVol02, which is
584 * mounted as /usr and has all of its extents on /dev/sdb1. If you pass /dev/sda into the
585 * function, both /var and /usr will be archived even though /usr is actually on/dev/sdb.
586 *
587 * - If the partition is part of a Volume Group that has Logical Volumes used in a mounted
588 * software raid device, it adds an entry to the linked list, copies to it the software raid
589 * device name and mount point, and sets check == 1.
