13 | mkrescue - make rescue floppy | ||
14 | !!SYNOPSIS | ||
15 | |||
16 | |||
17 | __/usr/sbin/mkrescue__ - make a bootable rescue floppy | ||
18 | using the existing kernel and any initial | ||
19 | ramdisk. | ||
20 | !!DESCRIPTION | ||
21 | |||
22 | |||
23 | __mkrescue__ assumes that the present running system was | ||
24 | successfully booted using the __lilo__ boot loader, and | ||
25 | that the specification for the kernel and any initial | ||
26 | ramdisk are in __/etc/lilo.conf__. This command will make | ||
27 | a bootable 1.44M rescue floppy which uses the current | ||
28 | kernel, any initial ramdisk, and the | ||
29 | __ | ||
30 | !!OPTIONS | ||
31 | |||
32 | |||
33 | __--device __ | ||
34 | |||
35 | |||
36 | Make the floppy on a device other than /dev/fd0. The floppy | ||
37 | disk will always be made to boot on BIOS device code 0x00 | ||
38 | (A: drive), without regard to the drive on which it is | ||
39 | created. | ||
40 | |||
41 | |||
42 | __--fast__ | ||
43 | |||
44 | |||
45 | Use a faster method of creating the boot floppy. This | ||
46 | involves first creating a 1.44M file mounted using a | ||
47 | loopback device, then copying the file to the disk. | ||
48 | Currently, loopback device 'loop4' must be free for this | ||
49 | option to be used. | ||
50 | |||
51 | |||
52 | __--fs [[ ext2 | msdos | minix ]__ | ||
53 | |||
54 | |||
55 | Specify the type of filesystem to create on the drive. | ||
56 | __ext2__ is the default, but | ||
57 | __ | ||
58 | |||
59 | |||
60 | __--help__ | ||
61 | |||
62 | |||
63 | Print a short usage synopsis, including a list of command | ||
64 | options. | ||
65 | |||
66 | |||
67 | __--initrd __ ''and'' __--kernel | ||
68 | __ | ||
69 | |||
70 | |||
71 | These options, which must be used together, allow | ||
72 | specification of an arbitrary kernel file and initial | ||
73 | ramdisk file to be used on the created boot floppy. Be sure | ||
74 | you know what you are doing before you use these | ||
75 | options. | ||
76 | |||
77 | |||
78 | __--nocompact__ | ||
79 | |||
80 | |||
81 | For faster kernel loading from a floppy, LILO map compaction | ||
82 | is normally enabled. This option will disable map compaction | ||
83 | by omitting the lilo | ||
84 | |||
85 | |||
86 | __--noformat__ | ||
87 | |||
88 | |||
89 | Suppresses creation of a new filesystem on the boot floppy. | ||
90 | This option may be used __only__ when you know that the | ||
91 | floppy you will be writing upon is formatted with the same | ||
92 | filesystem as specified by | ||
93 | __ | ||
94 | |||
95 | |||
96 | __--root __ | ||
97 | |||
98 | |||
99 | Specify the root filesystem for the kernel on the boot | ||
100 | floppy. The currently mounted root is the default, if this | ||
101 | option is not specified. | ||
102 | |||
103 | |||
104 | __--version__ | ||
105 | |||
106 | |||
107 | Print the version number of 'mkrescue', then | ||
108 | terminate. | ||
