This patch is reducing the size of the ramdisk image generated by the
ironic-agent element. It does remove extra packages (graphical stuff,
dev stuff, miscs, docs, etc...) and purges directories that are not
needed for a ramdisk (like /boot since it boots using an external
kernel)
Currently it was tested generating a Fedora 22 image and reduced the
size of the final image from 464 MB to 211MB compacted (54% decrease).
I was able to boot a VM with 1.3 GiB of ram instead of the previous 3 GiB
needed.

The script for ironic-agent utilizes curl, however an extremely
minimal system may not have it, and as such we should list it as
a package that must be installed to support the element.

As described in the comments, sfdisk was rewritten for util-linux 2.26
(as shipped in F22) and now interprets arguments a sectors, rather
than cylinders.
The current partitioning line is "1 - - *" (start/size/type/bootable)
which means you start getting:
---
/usr/sbin/grub2-install: warning: this msdos-style partition label has
no post-MBR gap; embedding won't be possible.
/usr/sbin/grub2-install: warning: Embedding is not possible. GRUB can
only be installed in this setup by using blocklists. However,
blocklists are UNRELIABLE and their use is discoura ged..
/usr/sbin/grub2-install: error: will not proceed with blocklists.
---
when building images, because the start is interpreted by the new
sfdisk as sector 1 and it crams the partition right next to the MBR.
Specifying "-" for the size is undefined in the man page; even reading
the source it's not totally clear what "-" for the size does [2]. In
any case, the alignment is wrong in sectors or cylinders; we want to
be a multiple of 4KiB for best performance.
The intent here is to create one single, Linux, bootable, partition
taking up the whole disk starting at 1MiB, so "2048 + L *" makes this
clear.
We use the -uS argument to ensure both versions treat this start-value
as a sector offset (newer sfdisk essentially ignores the argument).
As described in the comments, bugs in the older sfdisk necessitate
usage of "--force".
Although we could choose more or less, it seems most common to align
to a 1MiB boundary (i.e. starting at sector 2048). libguestfs has
some disucssion around --alignment and where it sets it's default to
this [3]. The 2.26-era sfdisk also defaults to putting partitions
here. 1MiB should be enough for GPT schemes in the future as well.

The resize module is problematic for using grub on very large root

Story: 2000175
Using "yum --downloadonly" breaks the abstraction of
"install-packages" because it downloads to the yum cache. It also
acts funny if the package is already there.
Add an argument to "-d" which is the directory to download to. dnf
has "download" built in, and for the old case use yumdownloader which
acts about the same. Ensure it is installed, since it comes in
yum-utils.
Also a slight cleanup of the getopt parsing so it's easier to have the
required argument for -d
Thus we can remove most of the stuff in 15-remove-grub. The check for
centos6 and it's lack of grub2 is clarified. All the stuff about
having to remove the package, purging the cache etc so yum gets the
right thing is no longer relevant. The long section of commented out
code at the end is also removed for clarity.
I tested this with an F21, F22 & centos (6) build

There is a common pattern of if init_system == foo then install init

When building an image having the elements debian and vm, cloud-init
fails with:
ci-info: !!!!!!!!Net device info failed!!!!!!!!
Looking at the source code, it executes ifconfig to gather informations
but the `debian` elements does not provide it. There is also no DHCP
client available which is rather painful.
Install isc-dhcp-client to provide a DHCP client.
Install net-tools to provide ifconfig, required by cloud-init.

Passing a source-repositories ref of "*" should signal fetching all

Modify the install-packages for yum to use this variable when set, but
default back to "yum" to retain the status-quo.

Installing Python to a ramdisk takes quite a long time because of
the way dracut checks for dependencies of every single file
installed. We could avoid that, but then we might miss a required
library file.
This change alters the installation method to speed up
the process. First, it creates a list of files that are needed and
then installs them all at once using inst_multiple instead of calling
inst on each file separately. This doesn't make a huge difference,
but in my testing it is marginally faster.
Second, and more significantly, we don't need the *.pyo and *.pyc
files as those are simply an optimization to speed up module
loading. Because the deploy ramdisk is a short-lived operation,
we probably lose more time transferring those extra files to the
target system than we save in improved load times.
In my testing, these two changes netted about a 20% improvement
in build times, and about 13% decrease in image size.

This patch is adds a new grub2 element that installs the
