I didn't actually see this, and in general we try and avoid dependencies
on random 3rd party webservices. Can we mirror FreeBSD locally like we
do with Debian?

I think for the final deployment we would want a specific version here.
IIRC the "current" stuff used with DiVersion is vestigial and no longer
used (or perhaps a standalone-mode-ism).

(or perhaps there is something which that graphic from 00/11 should be
telling me which I can't decipher)

I suppose this is some clever way to avoid unnecessary reinstalls?

Isn't get_mfsbsd the same as get_set("mfsbsd.img") ?

This relies on the webserver and the controller having a shared NFS view
of the world, which I'm not sure is always true?

Did you not already do this and/or can't you do it while tailoring
rather than after first boot?

Likewise.

That was remarkably painless, I thought it would be much worse!
