|
---|
30 |
|
---|
31 | pbmkbm - a project-builder.org utility to make boot media
|
---|
32 |
|
---|
33 | =head1 DESCRIPTION
|
---|
34 |
|
---|
35 | pbmkbm creates a bootable media (CD/DVD, USB device, Network, tape, ...)
|
---|
36 | with a minimal distribution in it, suited for building packages for example.
|
---|
37 | It aims at supporting all distributions supported by project-builder.org
|
---|
38 | (RHEL, RH, Fedora, OpeSUSE, SLES, Mandriva, ...)
|
---|
39 |
|
---|
40 | It is inspired by work done by Jean-Marc André around the HP SSSTK and
|
---|
41 | aim at replacing the mindi project (http://www.mondorescue.org), but
|
---|
42 | fully integrated with project-builder.org
|
---|
43 |
|
---|
44 | pbmkbm works in different phases. The first one is to check all
|
---|
45 |
|
---|
46 | pbmkbm needs to gather a certain number of components that could come
|
---|
47 | from various sources and could be put on a different target media.
|
---|
48 | We need a kernel, an initrd/initramfs for additional modules and init script,
|
---|
49 | a root filesystem and a boot configuration file.
|
---|
50 | Kernel, modules could come either from the local installed system
|
---|
51 | (typically for disaster recovery context) or from a kernel package of a
|
---|
52 | given configuration.
|
---|
53 | Utilities could come from busybox, local utilities or set of packages.
|
---|
54 | The root filesystem is made with them.
|
---|
55 | The initrd/initramfs could be made internaly or by calling dracut.
|
---|
56 | THe boot config file is generated from analysis content or provided externally.
|
---|
