Lucas Alvares Gomes 1181fb8543 Reduce the size of the ironic-agent ramdisk 
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.

ironic-agent

Builds a ramdisk with ironic-python-agent. More information can be found at:

https://git.openstack.org/cgit/openstack/ironic-python-agent/

Beyond installing the ironic-python-agent, this element does the following:

  • Installs the dhcp-all-interfaces so the node, upon booting, attempts to obtain an IP address on all available network interfaces.
  • Disables the iptables service on SysV and systemd based systems.
  • Disables the ufw service on Upstart based systems.
  • Installs packages required for the operation of the ironic-python-agent::

    qemu-utils parted hdparm util-linux genisoimage

  • When installing from source, python-dev and gcc are also installed in order to support source based installation of ironic-python-agent and its dependencies.

Note

Using the ramdisk will require at least 1.5GB of ram
