Title:
if ip is specified on cmdline, networking should be brought up in
initramfs
Status in cloud-initramfs-tools package in Ubuntu:

Status in initramfs-tools package in Ubuntu:

Bug description:
if the initramfs has 'ip=' on the cmdline, it is arguable that we
should bring the respective interface up as indicated.
Currently, initramfs only does this if something thinks it should.
Ie, open-iscsi might do it, or some other things might call 'configure_networking'.
But it seems reasonable that if the user put 'ip=' on the cmdline then they wanted that to happen in initramfs.
Additionally, one feature i'd like to have (admittedly for debug purposes) is the ability to write the /run/network/initramfs-persistent-iface that is used at least by open-iscsi to say "do not bring this interface down".
I've done this before, the code to do it is available in intramfs-tools style module at
http://bazaar.launchpad.net/~smoser/maas/maas-pkg-test/files/head:/ephemtest-vivid/initrd-updates/
that is explicitly to patch over an existing initramfs (no 'hooks'
directory).
