Bug Description

I have a few disks on my system, but I'm only setting up one filesystem - /dev/sda formatted as ext4 and set to be mounted at /.

This is with an EFI system and 2.0.0~beta6+bzr5073-0ubuntu1~xenial1.

This may not be a valid config - I think I need a /boot/efi partition too.

It would be nice if MAAS would tell me this isn't a valid config, since it tries to do that when I don't have a / at all.

You can see this does cause an issue with grub-install from the log here:
