After inspecting the derivations, the issue is from the file
’config.scm-builder’ which differs by:
(define-public %sysconfdir "/usr/local/etc")
vs
(define-public %sysconfdir "/etc")
What did I do wrong? From where does this difference come? How can I
fix it?
Below, the different commands to spot out the issue.
Cheers,
