| 35 |
|
|---|
| 36 | pbmkbm - a project-builder.org utility to make boot media
|
|---|
| 37 |
|
|---|
| 38 | =head1 DESCRIPTION
|
|---|
| 39 |
|
|---|
| 40 | pbmkbm creates a bootable media (CD/DVD, USB device, Network, tape, ...)
|
|---|
| 41 | with a minimal distribution in it, suited for building packages for example.
|
|---|
| 42 | It aims at supporting all distributions supported by project-builder.org
|
|---|
| 43 | (RHEL, RH, Fedora, OpeSUSE, SLES, Mandriva, ...)
|
|---|
| 44 |
|
|---|
| 45 | It is inspired by work done by Jean-Marc André around the HP SSSTK and
|
|---|
| 46 | aim at replacing the mindi project (http://www.mondorescue.org), but
|
|---|
| 47 | fully integrated with project-builder.org
|
|---|
| 48 |
|
|---|
| 49 | pbmkbm works in different phases. The first one is to check all
|
|---|
| 50 |
|
|---|
| 51 | pbmkbm needs to gather a certain number of components that could come
|
|---|
| 52 | from various sources and could be put on a different target media.
|
|---|
| 53 | We need a kernel, an initrd/initramfs for additional modules and init script,
|
|---|
| 54 | a root filesystem and a boot configuration file.
|
|---|
| 55 | Kernel, modules could come either from the local installed system
|
|---|
| 56 | (typically for disaster recovery context) or from a kernel package of a
|
|---|
| 57 | given configuration or a referenced content.
|
|---|
| 58 | Utilities could come from busybox, local utilities or set of packages.
|
|---|
| 59 | The root filesystem is made with them.
|
|---|
| 60 | The initrd/initramfs could be made internaly or by calling dracut.
|
|---|
| 61 | The boot config file is generated from analysis content or provided externally.
|
|---|
