33rpmbootstrap - creates a chrooted RPM based distribution a la debootstrap, aka Virtual Environment (VE)
34
35=head1 DESCRIPTION
36
37rpmbootstrap creates a chroot environment (Virtual Environment or VE)
38with a minimal distribution in it, suited for building packages for example.
39It's very much like debootstrap but for RPM based distribution.
40It aims at supporting all distributions supported by project-builder.org
41(RHEL, RH, Fedora, OpeSUSE, SLES, Mandriva, ...)
42
43It is inspired by work done by Steve Kemp for rinse (http://www.steve.org.uk/),
44and similar to mock, but fully integrated with project-builder.org
45(which also supports rinse and mock).
46
47=head1 SYNOPSIS
48
49rpmbootstrap [-vhmqpdk][-s script][-i iso][-a pkg1[,pkg2,...]] distribution-version-arch [target-dir] [mirror [script]]
50
51rpmbootstrap [--verbose][--help][--man][--quiet][--print-rpms][--download-only]
52[--keep][--script script][--iso iso][--add pkg1,[pkg2,...]] distribution-version-arch [target-dir] [mirror [script]]
53
54=head1 OPTIONS
55
56=over 4
57
58=item B<-v|--verbose>
59
60Print a brief help message and exits.
61
62=item B<-h|--help>
63
64Print a brief help message and exits.
65
66=item B<--man>
67
68Prints the manual page and exits.
69
70=item B<-q|--quiet>
71
72Do not print any output.
73
74=item B<-p|--print-rpms>
75
76Print the packages to be installed, and exit.
77Note that a target directory must be specified so rpmbootstrap can determine
78which packages should be installed, and to resolve dependencies.
79The target directory will be deleted.
80
81=item B<-d|--download-only>
82
83Download packages, but don't perform installation.
84
85=item B<-k|--keep>
86
87Keep packages in the cache dir for later reuse. By default remove them.
88
89=item B<-s|--script script>
90
91Name of the script you want to execute on the related VEs after the installation.
92It is executed in host environment.
93You can use the chroot command to execute actions in the VE.
94
95=item B<-i|--iso iso_image>
96
97Name of the ISO image of the distribution you want to install on the related VE.
98
99=item B<-a|--add pkg1[,pkg2,...]>
100
101Additional packages to add from the distribution you want to install on the related VE
102at the end of the chroot build.
103
104=back
105
106=head1 ARGUMENTS
107
108=over 4
109
110=item B<distribution-version-arch>
111
112Full name of the distribution that needs to be installed in the VE. E.g. fedora-11-x86_64.
113
114=item B<target-dir>
115
116This is the target directory under which the VE will be created.
117Created on the fly if needed.
118If none is given use the default directory hosting VE for project-builder.org
119(Cf: vepath parameter in $HOME/.pbrc)
120
