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

72=head1 OPTIONS
73
74=over 4
75
76=item B<-v|--verbose>
77
78Print a brief help message and exits.
79
80=item B<-h|--help>
81
82Print a brief help message and exits.
83
84=item B<--man>
85
86Prints the manual page and exits.

89
90Do not print any output.
91
92=item B<-t|--type boot-type>
93
94Type of the boot device to generate. A boot-type can be:
95
96=over 4
97
98=item B<iso>
99
100Generate an ISO9660 image format (suitable to be burned later on or loopback mounted. Uses isolinux.
101
102=item B<usb>
103
104Generate a USB image format (typically a key of external hard drive). Uses syslinux.
105
106=item B<pxe>
107
108Generate a PXE environement (suitable to be integrated in a PXElinux configuration). Uses pxelinux.
109
110=back
111
112=item B<-d|--device device-file>
113
114Name of the device or file on which you want to create the boot media.
115

118This is the boot method to use to create the boot media. A boot-method can be:
119
120=over 4
121
122=item B<native>
123
124Use the tools of the native distribution to create the boot media. No other dependency.
125
126=item B<ve>
127
128Use the project-builder.org virtual environment notion to create the boot media. No other dependency outside of the project.
129
130=item B<busybox>
131
132Use the busybox tool to create the boot media. Cf: L<http://www.busybox.net>
133
134=item B<dracut>
135
136Use the dracut tool to create the boot media. Cf: L<http://www.dracut.net>
137
138=back
139
140=item B<-s|--script script>
141
142Name of the script you want to execute on the related boot media at the end of the build.
143
144=item B<-a|--add pkg1[,pkg2,...]>
145
146Additional packages to add from the distribution you want to install on the related boot media
147at the end of the build.
148
149=item B<-m|--machine os-ver-arch>
150
151This is the target tuple operating system-version-architecture for which you want to create the boot media.
152
153=back
154
155=head1 ARGUMENTS
156
157target-dir is the directory under which the boot media will be build.

163=head1 EXAMPLE
164
165To setup a USB busybox based boot media on the /dev/sdb device for a Fedora 12 distribution with an i386 architecture issue:
166
167pbmkbm -t usb -d /dev/sdb -m fedora-12-i386 -b busybox
168
169To setup an ISO image under /tmp for a RHEL 6 x86_64 distribution issue using the native environment:
170
171pbmkbm -t iso -d /tmp -m rhel-6-x86_64 -b ve
