| 31 | =head1 NAME
|
|---|
| 32 |
|
|---|
| 33 | rpmbootstrap - creates a chrooted RPM based distribution a la debootstrap, aka Virtual Environment (VE)
|
|---|
| 34 |
|
|---|
| 35 | =head1 DESCRIPTION
|
|---|
| 36 |
|
|---|
| 37 | rpmbootstrap creates a chroot environment (Virtual Environment or VE) with a minimal distribution in it,
|
|---|
| 38 | suited for building packages for example. It's very much like debootstrap but for RPM based distribution.
|
|---|
| 39 | It aims at supporting all distributions supported by project-builder;org (RHEL, RH, Fedora, OpeSUSE, SLES, Mandriva, ...)
|
|---|
| 40 |
|
|---|
| 41 | It is inspired by work done by Steve Kemp for rinse (http://www.steve.org.uk/), and similar to mock, but fully integrated with project-builder.org (which also supports rinse and mock).
|
|---|
| 42 |
|
