Are you planning on using TFTP/NFS just for a faster development path
or as your final target solution?

It should be possible with a few hacks, but since we use at least the
first partition to save the u-boot config (for snappy_ab, snappy_boot,
snappy_cmdline and snappy_mode), the update mechanism will not work

Not for the oem that Ogra created, but the oem owner can specify
whatever other u-boot configuration by default.

We should be announcing Snapcraft properly over the next few days, and
that tool will have an easy way for you to create snaps out of ubuntu
packages (or any other upstream project). The main missing piece atm
is getting the local development story in place (via a traditional
ubuntu container).

Should have more details for that later this week.
