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 default value was set in the centos7 element, but not
exported, which caused issues in rpm-distro. Also changed
a test in rpm-distro to only check for DIB_RELEASE > 22
if it's fedora.

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.

Using the default release for the Debian test-element leaves
us at the mercy of packaging problems in Debian unstable. Since
we only care if the image itself builds, use the safe choice of
Debian stable.

Adds support for Ubuntu and Debian to ironic-python-agent. This will
enable building ramdisk with Ubuntu and Debian as base OS.
Updated README to further clarify what the element does.

interfaces are not configured at all because specific interface files
are created but not sourced. This will result in the VMs running with
the loopback interface only
This is a regression, the problem was already fixed in the past, see commit

We have a bug where we are overriding the tmpdir cleanup with the docker
image rm cleanup. We should be doing both.

The resize module is problematic for using grub on very large root
partitions. It is also extremely slow on large partitions, and users are
likely better off creating new partitions in the empty space.

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

Docker can export root filesystems, which is what we want out of root
elements. Make a very simple passthrough element that will grab a docker
image and export it into a root filesystem.

We can already produce tarballs, which is the input format docker import
expects. This makes it trivial to add docker as an output format.

There is a common pattern of if init_system == foo then install init
script foo-service-init into /etc/init... Lets encode this pattern by
allowing elements to put files into init-scripts/init-system directories
and then copying the appropriate files for them.
