| 4 |
|
---|
| 5 |
|
---|
| 6 | 08/01
|
---|
| 7 | - when evaluating mountlist, skip drive entirely if it does not exist
|
---|
| 8 |
|
---|
| 9 | 07/14
|
---|
| 10 | - always exclude /devpts, /proc, /sys from mountlist
|
---|
| 11 |
|
---|
| 12 | 06/29/2004
|
---|
| 13 | - changed some char[] to *char
|
---|
| 14 | - drivelist is struct now, not char[][]
|
---|
| 15 |
|
---|
| 16 | 10/19/2003
|
---|
| 17 | - format_device() --- contract /dev/md/N to /dev/mdN to
|
---|
| 18 | overcome devfs problems
|
---|
| 19 |
|
---|
| 20 | 06/11
|
---|
| 21 | - added support for 5th column in mountlist.txt, for labels
|
---|
| 22 |
|
---|
| 23 | 05/08
|
---|
| 24 | - added save_mountlist_to_disk() and load_mountlist()
|
---|
| 25 | and misc other funcs from mondorestore.c
|
---|
| 26 |
|
---|
| 27 | 05/05
|
---|
| 28 | - added Joshua Oreman's FreeBSD patches
|
---|
| 29 |
|
---|
| 30 | 04/24
|
---|
| 31 | - added some assert()'s
|
---|
| 32 |
|
---|
| 33 | 04/23
|
---|
| 34 | - cleaned up evaluate_drive_within_mountlist() a bit
|
---|
| 35 |
|
---|
| 36 | 01/15/2003
|
---|
| 37 | - added code for LVM (Brian Borgeson)
|
---|
| 38 |
|
---|
| 39 | 10/19/2002
|
---|
| 40 | - added some comments
|
---|
| 41 |
|
---|
| 42 | 07/24/2002
