Please review this for a solution to #36. I've let it run through Hydra thoroughly, so no breakage expected.

I started wondering about that static list of Kasli variants. Is there a reason it can't be sourced from a directory listing of sinaraSystemsSrc, with a white/black list of variants to include/exclude in non-beta?

How would you define those "minimum ARTIQ version" requirements though?

How about putting the minimum ARTIQ version in the variant JSON itself?

Yes, that can be done.

Won't that break on ARTIQ-5?

...and on -6 bloat the channel expressions with all the generated sources for all variants?

For the non-beta case no sources are built but board-generated/artiq-targets.nix is still used because it contains the static variants list.

"artiq:board-generated-beta:generated-nix" is another generated-nix just like <artiq-fast> here. As there are no dependencies on the generated sources (yet), I'm still not sure if artiq-full evaluation will wait until all of the board-generated jobs have been tried.

Hmm, it's a bit heavy to add a new jobset for that on -5. Can we be more conservative here?

Won't this produce some spurious builds with inconsistent artiq-fast and artiq-board-generated versions?

I think there should be a single ARTIQ input to full-beta, i.e. board-generated needs to include the copy of fast that it used, and then full reuses it, in order to prevent de-synchronization.

I was wondering about that. Thank you for spelling it out. That will also result in yet more divergent codepaths between non-beta and beta.

If it diverges too much, just have two independent copies of the relevant Nix files. This will also help avoiding inadvertently breaking stable.

You can probably symlink and not copy.

Symlinking seems to break Nix restricted mode in which only /nix/store entries of known inputs are available to a build.
