Looked through hydra source and found command used to evaluate jobsets. Using a nix-shell sheband, to get the hydra package, we can run this locally without having a Hydra server running (it doesn’t use the DB). Made check.sh do this.

We were getting an infinite recursion error due to withNix trying to look up NIX_REMOTE using runScript instead of runCommand (runScript is our wrapper around runCommand, which uses withNix!)

Now it seems we have 2 problems:

• Files/strings referring to other paths. Might be solved with builtins.storePath and/or passAsFile. This is really the eval/build distinction.
• Can hydra do dynamic imports, e.g. import (runCommand ...).outPath?
• NIX_REMOTE gets invalid error on server, but not locally. Investigate after the above.
