commit e9bed5e9e7e4f9e6d92794fd159164cc0936a911
Author: Mathieu Othacehe <othacehe@gnu.org>

    tests: nix: Fix it.
    
    The <nix/config.nix> support has been removed in Nix 2.4:
    https://github.com/NixOS/nix/pull/4025. Rely on the store ping command 
instead
    to check that we can communicate with the daemon.
    
    * gnu/tests/package-management.scm (run-nix-test): Use the store ping 
command
    instead of building a dummy derivation.
