@jeanparpaillon Thanks! This looks great.

I'm working with @oestrich and @jjcarstens to get this change in. We're in an awkward place where we're doing a lot of testing with a modified version of NervesHub. See https://github.com/nerves-hub/nerves_hub_web/commits/2.0. We're working on docs and updates to describe the direction we're going in 2.0. The main reason for 2.0, though, is to let us break compatibility in a few areas to make implementing some features we really want much easier.

In summary, I suspect that we merge your PR to main, since you're actively testing so it should work. We'll also merge to the 2.0 branch and do our testing. I'll defer to Eric and Jon since there more into the code here than I am.

@fhunleth thanks for the heads up. You may have noticed I have arbitrarily set a minimal fwup version in the code that need to be adjusted with regard to the PR in fwup.

[jeanparpaillon]

@fhunleth I've identified a bug in the code and just updated the PR: when creating firmware archive, ensure meta.conf. and meta.conf are the first files in the archive

[jeanparpaillon]

@fhunleth same fix pushed to nerves-project/nerves#857

[fhunleth]

FYI - I switched the destination branch to maint-v1.0. When this functionality gets added, I'd like to get it in 2.0 as well.

[jjcarstens]

So sorry this took so long! Will add to main shortly as well
