Martin André bc2199144e Selectively prune /root for ironic-agent ramdisk 
Previously all files in /root were ignored when building the
ironic-agent ramdisk. This prevented for example to use the
local-config element to connect to the ramdisk via ssh as root user.

This commit change the exclude rule on /root to only ignore the
/root/.cache directory.

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.

This element outputs three files:

  • $IMAGE-NAME.initramfs: The deploy ramdisk file containing the ironic-python-agent (IPA) service.
  • $IMAGE-NAME.kernel: The kernel binary file.
  • $IMAGE-NAME.vmlinuz: A hard link pointing to the $IMAGE-NAME.kernel file; this is just a backward compatibility layer, please do not rely on this file.

Note

The package based install currently only enables the service when using the systemd init system. This can easily be changed if there is an agent package which includes upstart or sysv packaging.

Note

Using the ramdisk will require at least 1.5GB of ram
