I'd love to try and build it for aarch64-linux, but I'm not sure how to do so (and test the result) on an x86_64-linux machine. According to the heliocron README, aarch64 support should be good.

i use binfmt on x86 to build and run aarch64-linux

from CI you can see that heliocron builds fine on aarch64-linux

Oh nice, that's really cool! Thanks.

@TheColorman can you please squash your commits into heliocron: init at 0.8.1, so there should be just two commits

• maintainers: add TheColorman
• heliocron: init at 0.8.1

usually multiple commits is fine, but for init PR's and when commits are so small, it's better to reduce noise.

[kirillrdy]

thank you !

Guess I can call myself a nixpkgs maintainer now 😅
