---|
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
|
---|
43 | - created
