Nice work, thanks for sharing!

IIUC, (guix workflows) from the tarball you sent executes workflows in
the current environment, as opposed to creating a derivation that would
actually perform the workflow.  What motivated this approach?

Workflows could compiled to derivations, which in turn could be “built”,
and their build result would be the workflow’s output file.

I guess in practice it only works if users of the cluster can build
derivations on the cluster and have them scheduled on compute nodes.

Thoughts?

Thank you!
