You mention 'grub', is this at all specific to grub? or is this just kernel command line specific.

Kernel command line specific as documented here https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt. I just configure this via grub.

it would be really great for pxe-less enviroments to fix this issue. MaaS has no method to operate in environments without dhcp without this patch.
MaaS is capable of adding in the proper kernel command line options, however cloud-init pukes when it doesn't get dhcp or static as a variable.

cloud-init pre-networking fails when grub is configured to use a static IP with the 'autoconf' field set to 'none' (https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt).
Cloud provider: vsphere
Static IP is configured here (/etc/default/grub).
https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt
off or none: don't use autoconfiguration (do static IP assignment instead)

ValueError: Unexpected value for PROTO: none
Workarounds: Option 1. Change the grub config to use 'dhcp' even though it defines most of the fields statically GRUB_CMDLINE_LINUX=ip=10.121.105.37::10.121.104.1:255.255.252.0::eth0:dhcp
Option 2. Patch to normalize 'none' to 'static' (I'd guess there's a more proper fix further up the call) --- /usr/lib/python3/dist-packages/cloudinit/net/cmdline.py.orig 2018-08-03 15:44:11.204005997 +0000 +++ /usr/lib/python3/dist-packages/cloudinit/net/cmdline.py 2018-08-03 15:44:15.448006149 +0000 @@ -52,6 +52,8 @@ else: proto = 'static'
