fd2f55ee41 yum-minimal : install selinux policy packages
Install selinux policy packages as part of the base-installs.  selinux
is part of the base-system and the kernel boots by default in selinux
mode.

Without both of these, we can get in a situation where later scripts
(particuarly, some of the infra scripts) might install systemd-policy
without a base policy (targeted), leading to a messed up situation
where systemd will halt during boot due to missing policy files.

1d476dd994 Remove fedora-minimal/install.d/99-ramdisk
When the kernel gets installed on Fedora, the rpm post scripts call
"/bin/kernel-install" [1] to install it.  This is a script provided by
systemd.

However, in [2], Fedora ships a patch to kernel-install that makes a
call-out to /sbin/new-kernel-pkg -- the install script provided by
grubby [3]

Without grubby installed, systemd's kernel-install script goes off and
runs dracut plugins directly [4], which eventually creates the initrd.
For reasons that are not clearly explained, the initrd will end up in
a a "machine-id" sub-directory of /boot (possibly, so you can symlink
it?).  It is also called "initrd", even though it's an initramfs, for
historical reasons in dracut I think.

It is at this point that I think 99-ramdisk has been written to move
the generated initrd file back into /boot.  Later on, when we build
the image, we run grub-install and it picks up the kernel and the
initrd and installs everything.

grubby's new-kernel-pkg [6] it's very similar -- it uses dracut to
make the initramfs ... but in this case it is put in /boot and is
actually called initramfs.

The subtle change that led me down this path is that dracut has been
modified to have a "Recommends" for grubby for >F22 [7].  After
discussing this change with the author, it turns out it was *always*
intended to use the grubby-based kernel install scripts for Fedora --
our builds have been incorrect in not including the package.  The
author got sick of people removing the package and making unbootable
systems, hence the change.

Thus this removes the workarounds in 99-ramdisk and replace it with an
install of the grubby package.  grubby's kernel install script will
put the kernel & generated initramfs in /boot, and it will be
installed correctly via the usual grub install later when we build the
disk image.

I have built F22 & F23 fedora-minimal images with this and they boot.

b5bcb3b60e Add a yum-minimal element that just uses yum
The centos-minimal approach of using rinse does not, it turns out, work
on centos. That's a bummer. It's also rather heavyweight. Instead, with
minor machinations, we can just use yum itself pointed at a chroot.

Also adding fedora-minimal element which creates a fedora image using
the new yum-minimal approach.
