RPM configuration via release pkg
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The equivalent of `redhat-release` package on ordinary redhat appears to be `sl-release` on Scientific Linux machines.

::

    [blyth@belle7 ~]$ sudo yum --enablerepo=epel search sl-release
    sl-release.i386 : Scientific Linux release file
    sl-release-notes.noarch : Scientific Linux release notes files

::

    [blyth@belle7 ~]$ rpm -ql sl-release

chroot jail

`mock -r configname`
-----------------------

* https://fedoraproject.org/wiki/Using_Mock_to_test_package_builds#Using_mock_as_a_chroot_sandbox_tool
* http://docs.fedoraproject.org/en-US/Fedora_Draft_Documentation/0.1/html-single/Packagers_Guide/index.html

Mock can be used to create chroots for testing things, not just building packages. 
Create a config file that points to the repo(s) of your choice, where your test packages are

::

    mock -r <config-name> --init
    mock -r <config-name> --install <your packages>
    mock -r <config-name> --shell

Why use mock to shell, why not chroot directly? 

   * Using mock to "shell" will allow mock to create the mountpoints you'll
     probably need inside the chroot.
