[r=rvb][bug=1050523][author=smoser] cleanup of kernel command line arguments, add iscsi_inititator param
Move some options to purpose specific, drop some, change some.
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.
