[Bug 1684039] Re: iBFT network configuration does not correctly populate PROTO=dhcp in /run/net-*.conf which breaks cloud-init

[Eric Desrochers]

Debian maintainer has committed the patch ^. [1]

Next step is to make sure Artful has the fix now, and then the SRU for
all affected supported stable releases can start.

Trent, feel free to contact me once Artful has the change, and I'll
sponsor the SRU.

    initramfs: populate PROTO= entry in /run/net-*.conf from iBFT
    
    When booting from iBFT, set the PROTO= entry in /run/net-*.conf
    accordingly, so that other tools, such as cloud-init, can use that
    information. (cloud-init fails if the current PROTO=none is used.)
    
    Closes: #866213

Title:
  iBFT network configuration does not correctly populate PROTO=dhcp in
  /run/net-*.conf which breaks cloud-init

  Fix Released

Bug description:
  When booting with iBFT, the network configuration is performed by
  open-iscsi as part of initramfs.local-top instead of by klibc-
  ipconfig.  This includes populating /run/net-*.conf which is consumed
  among other things, by cloud-init.

  Currently no attempt to determine PROTO is made, and PROTO=none is
  hard coded into the file which cloud-init does not recognise and
  crashes out.

  Further to this, open-iscsi in the current version (xenial through
  zesty) does not correctly parse the iBFT origin into the boot protocol
  in "iscsistart -f" and always returns "STATIC".  This is fixed
  upstream.
