[Scott Moser <smoser@xxxxxxxxxx>]

The proposal to merge lp:~smoser/maas/kernel-cmdline-cleanup into lp:maas has been updated.

Description changed to:

cleanup of kernel command line arguments, add iscsi_inititator param

This generally cleans up the parameters that we pass on the kernel command
line.

ephemeral/commissioning:
 * add iscsi_initiator: this was always supposed to be required, but 12.04
   initramfs seem to work without it, so we didn't have it. 12.10 fail
   to configure the iscsi target in the initramfs without it. (LP: #1050523)
 * change url= to cloud-config-url=<preseed_url>
   This was really just re-named to cloud-config-url. cloud-init supports
   both 'url=' and 'cloud-config-url', but cloud-config-url is preferable
   as it is obviously more explicit in purpose.
 * change ip=dhcp to ip=::::<hostname>
   LP: #1046405 has more information, but this is how you would specify
   that the initramfs's dhcp client should specify hostname
 * add overlayroot=tmpfs
   cloud images for quantal now use the overlayroot package to accomplish
   read-only root. 12.04 images used a un-packaged earlier version that
   was hard-coded in the images to on. 12.10 and later need a kernel param
   to enable it.

move to install specific:
 netcfg/choose_interface, hostname, domain, text, priority, auto, locale

common:
 * add to intel: 'console=tty1 console=ttyS0'.
   This should log kernel messages to both serial console and graphical
   console if it is present. Note, the kernel assigns /dev/console to
       the last valid argument.
 * add 'nomodeset' to not switch video mode
 * remove 'suite'. Nothing that I am aware of reads this.

Other:
 * add 'SAY' of the kernel cmdline.  At least in testing with kvm
   and -curses, this is very helpful as it goes to wherever the bios
   console is, and you can see it even if 'console=ttyS0' is given
   and the kernel's log of that information goes elsewhere.
