Hi
Over all a very good initiative, but i have some concerns - sorry if they
have already been addressed (i couldn't find it).
With this mirroring the installed firmware in being able to communicate
that there are multiple firmware types and versions,
i think it could be worth being super-duper clear on that the contents of
these lists describe a set of firmware files that would get applied
together when triggering an update.
(...and is not to be used to contain multiple versions of the same thing).
A naive implementer might be tempted to list all versions offered, only to
find out the update operation has no way of saying to what version.
I also think it is a mistake to only support, possible even to require,
some online repository for firmware.
I think it would be very good to be able to supply the firmware file(s)
directly from the client.
Files tend to stick around much longer than the services that served them
most of the time.
Currently a lot of firmware updates are simply performed by "printing" a
file with some magic (often PJL) in it.
Also think of use in air-gapped environments, not just post-support-window
devices.
With no standard on what a repository is, there is no guarantee i could
deploy my own.
Br,
Anton
