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 |
---|
122 | - first incarnation |
