5
608/01
7- when evaluating mountlist, skip drive entirely if it does not exist
8
907/14
10- always exclude /devpts, /proc, /sys from mountlist
11
1206/29/2004
13- changed some char[] to *char
14- drivelist is struct now, not char[][]
15
1610/19/2003
17- format_device() --- contract /dev/md/N to /dev/mdN to
18 overcome devfs problems
19
2006/11
21- added support for 5th column in mountlist.txt, for labels
22
2305/08
24- added save_mountlist_to_disk() and load_mountlist()
25 and misc other funcs from mondorestore.c
26
2705/05
28- added Joshua Oreman's FreeBSD patches
29
3004/24
31- added some assert()'s
32
3304/23
34- cleaned up evaluate_drive_within_mountlist() a bit
35
3601/15/2003
37- added code for LVM (Brian Borgeson)
38
3910/19/2002
40- added some comments
41
4207/24/2002
43- created
