|
---|
24 | 07/27
|
---|
25 | - if the user is foolish enough to use /dev/md0 as boot device,
|
---|
26 | call lilo -M /dev/hda to make sure lilo does its job properly
|
---|
27 | - better NFS+nuke support
|
---|
28 |
|
---|
29 | 07/20
|
---|
30 | - use backup's i-want-my-lvm file
|
---|
31 | - be sure to use archives' raidtab when restoring
|
---|
32 |
|
---|
33 | 07/18
|
---|
34 | - use /tmp/isodir for NFS if DR mode
|
---|
35 | - better support of users who boot from LVM CD and nuke-restore non-LVM backups
|
---|
36 |
|
---|
37 | 07/12
|
---|
38 | - bugfix to allow user to burn ISOs to CDs and restore from CDs (not original src)
|
---|
39 |
|
---|
40 | 06/29
|
---|
41 | - mount ext3 partitions as ext2, just in case :)
|
---|
42 |
|
---|
43 | 06/26
|
---|
44 | - delete make_relevant_partition_bootable()
|
---|
45 |
|
---|
46 | 06/19
|
---|
47 | - futzed with the call to mount floppy, to stop it from locking up on my AMD64 system
|
---|
48 |
|
---|
49 | 06/14
|
---|
50 | - shell out to /mnt/RESTORING chroot in order to let user install GRUB
|
---|
51 | manually if automatic GRUB installation fails
|
---|
52 |
|
---|
53 | 06/15
|
---|
54 | - Added check for different 'isodir' chosen by user than stored in the archive
|
---|
55 | Conor Daly <conor.daly@met.ie>
|
---|
56 |
|
---|
57 | 04/17
|
---|
58 | - replaced INTERNAL_TAPE_BLK_SIZE with bkpinfo->internal_tape_block_size
|
---|
59 |
|
---|
60 | 04/09
|
---|
61 | - don't try to mount CD if tape bkp
|
---|
62 |
|
---|
63 | 04/03
|
---|
64 | - trying to copy tmp/mondo-restore.cfg to itself - silly! - fixed
|
---|
65 |
|
---|
66 | 04/02
|
---|
67 | - when extracting cfg file and mountlist from all.tar.gz (tape copy),
|
---|
68 | use block size of INTERNAL_TAPE_BLK_SIZE, not TAPE_BLOCK_SIZE
|
---|
69 |
|
---|
70 | 02/21
|
---|
71 | - don't use 'mv -v' cos Busybox won't support it
|
---|
72 |
|
---|
73 | 02/09
|
---|
74 | - make hole for cfg file before moving it (line 2094 or so)
|
---|
75 |
|
---|
76 | 02/03
|
---|
77 | - changed a couple of refs to filelist.full, to filelist.full.gz
|
---|
78 |
|
---|
79 | 01/16/2004
|
---|
80 | - instead of copying filelist, use 'ln -sf' to link to original;
|
---|
81 | saves space
|
---|
82 |
|
---|
83 | 11/20/2003
|
---|
84 | - also retrieve /tmp/mountlist.txt if user wants
|
---|
85 |
|
---|
86 | 11/16
|
---|
87 | - fixed NFS path bug affecting the extractions of filelist/biggielist
|
---|
88 | during selective restore
|
---|
89 |
|
---|
90 | 11/02
|
---|
91 | - fixed mount_cdrom() to run properly w/ nfs restores
|
---|
92 | - mount_device() returns 0 if swap mount fails cos swap isn't crucial
|
---|
93 |
|
---|
94 | 10/17
|
---|
95 | - run_grub() uses MNT_RESTORING instead of "/mnt/RESTORING"
|
---|
96 |
|
---|
97 | 10/26
|
---|
98 | - cleaned up run_grub()
|
---|
99 |
|
---|
100 | 10/25
|
---|
101 | - fixed mount_cdrom() to run properly w/ nfs restores
|
---|
102 |
|
---|
103 | 10/21
|
---|
104 | - mount_device() returns 0 if swap mount fails cos swap isn't crucial
|
---|
105 |
|
---|
106 | 10/15
|
---|
107 | - run_grub() now uses its initiative instead
|
---|
108 | of calling grub-install
|
---|
109 |
|
---|
110 | 10/10
|
---|
111 | - don't leave copies of filelist.full lying around, clogging up
|
---|
112 | the ramdisk, there's a good fellow :-)
|
---|
113 |
|
---|
114 | 10/02
|
---|
115 | - added 'dvd' to the range of media types I'll understand
|
---|
116 | - fixed iso->cdr problem (thanks, Stan Benoit & Fred Beondo)
|
---|
117 |
|
---|
118 | 09/24
|
---|
119 | - try lots of tape devs if /dev/st0 fails
|
---|
120 |
|
---|
121 | 09/23/2003
