Oh, I see the error message you gave above reads: the group `"guix-builders"' Note the extra double quotes. Could it be that the script that launches guix-daemon does something that amounts to: guix-daemon '--build-users-group="guix-builders"' That is, it leaves the double quotes as is in the argument? Thanks, Ludo’.
