eval-machines: remove .drv file which pulls in unneeded deps

all credit goes to @delroth - proposed in #69 (comment)

I'm running this since quite some time on my systems, and it's a huge time (and bandwidth)-saver.

Thanks for this!
It likely requires that we internally wrap morph with other build targets, since we actively use the drv on the target machines, but that's not your headache. :) We just need to do some testing real quick - I'll be back for a probable merge soon.

This definitely requires at least a release-note, but overall I think it's a more sensible default for morph.

Great to hear! I agree this probably should be part of the release notes. I assume release notes are only on https://github.com/DBCDK/morph/releases, are they? Couldn't find those in the repo, otherwise I would have included in this PR ;-)

morph stopped pushing .drv files to targets, only the nix paths, leading to a much smaller amount of data to be transferred.

[johanot]

LGTM. Local tests are ok. We'll make sure to write something about this on the next release. Yes; release notes are currently on the Github Releases page only. We might change that at some point :-)

[flokli]

@johanot small nag - any plans to do the next release?

[johanot]

@flokli better late than never :) https://github.com/DBCDK/morph/releases/tag/v1.4.0
