Comment 20 for bug 1401190

Also worth noting that curtin runs:

curtin --install-deps install --config=configs/config-000.cfg --config=configs/config-001.cfg --config=configs/config-002.cfg --config=configs/config-003.cfg --config=configs/config-004.cfg http://10.10.4.221:5248/images/ubuntu/amd64/generic/trusty/release/root-tgz

and config-002.cfg contains the nvme device (unrelated to the above but looks like it will cause problems in the next step i.e. once we can get curtin to select the correct partition)

cat configs/config-002.cfg
