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). |

generically, it seems like it'd be nice to have a way to have the same functionality that open-iscsi.interface accomplishes but not tied to open-iscsi. Ie, the user may for any reason want to keep a network from getting re-configured by normal OS bringup. I used '/run/network/initramfs-persistent-iface' file to do that.
