fix(lib/checks): import path of each check

[steveej]

prior to this the values in the checks attrs weren't derivations.

marking as a draft as i'm still encountering an infinite recursion trying to use this.

the infinite recursion that i encountered is due to an intrinsic property of the module system, i.e. it's expected albeit not intuitive behavior. more in #56

[steveej]

here's a log of the infinite recursion: https://buildbot-nix-0.infra.holochain.org/#/builders/440/builds/2

consumer code: https://github.com/Holo-Host/holo-host/pull/50/files#diff-1178a2379e02f5b2a29bb1227f783cf9d8fbe901e51f0924f3ccaddb02c1a565R15

the infinite recursion happens when the nixos test imports from flake.nixosModules.

@phaer i suspect the infinite recursion in the consumer is an issue of how i mapped the imports. is there something i could learn from 3da8b35?

@steveej Not sure, I am reading this correctly. The infinite recursion might not be directly related to this PR, correct? Don't see anything obvious at first glance, a more minimal reproducer which demonstrates the problem would be appreciated !

[steveej]

@phaer yes it's reproducible without the changes here. see: #56

[matdibu]

I also just ran into this and I thought I was crazy

I've tested your PR and it seems to work

thank you for fixing this!

[phaer]

Thanks!
