I miss how to fetch this missing .drv. :-)


For example this evaluation built a recent enough Guix, right?

--8<---------------cut here---------------start------------->8---
$ wget -q -O - 'http://ci.guix.gnu.org/build/1943556' | jq '."derivation"'
--8<---------------cut here---------------start------------->8---

outputs the derivation file. But how do you fetch it?

I have not found in the Cuirass API doc. Maybe I missing the obvious.

Then, once I have downloaded this derivation, the old Guix should be
able to build it, right? No daemon issue?

--8<---------------cut here---------------start------------->8---
$ guix build "/gnu/store/bz1qqy225p1jlicwf07iiqr79icqddcv-guix-4de11dda7.drv"
--8<---------------cut here---------------start------------->8---

This will populate the store with a new guix. Then I need to pull as
root, in order to also update the daemon, right?

--8<---------------cut here---------------start------------->8---
# /gnu/store/<hash-returned-by-previous-build>-guix-4de11dda7/bin/guix pulll
--8<---------------cut here---------------start------------->8---

Is it possible?
We need to track on Cuirass one recent enough derivation of Guix for
each architecture, right?



All the best,
