This adds support, documentation, and testing for a [[repos.git]]
blueprint section that can be used to install files from a git
repository. It will create an rpm that will be added to the build,
and included in the metadata that can be downloaded. This allows you to
accurately keep track of the source of configuration files and extra
metadata that is added to the build.
The source repo and reference will be listed in the rpm's summary making
it easy to discover on the installed system.
Anaconda, Lorax, lorax-composer, and livemedia-creator can all now run
with SELinux in Enforcing mode. It does not need to be disabled and if
there are denials they should be reported as a bug.
Log the current state of SELinux when starting, update the
documentation.
If we leave the root account w/o a password people will use it that way,
leading to insecure images. Also if we use a default password. So lock
the root account in the templates.
Users will need to do one of these things:
1. Use [[customizations.user]] in their blueprint to configure root or
another user.
2. Use [[customizations.sshkey]] to set a key for root
2. Install a package that configures a user at install time
3. Install a package that sets up a user at boot time (eg. cloud-init)
This also drops the auth line from the kickstart templates, allowing it
to use the default password algoritm instead of md5.
