Return a service that runs the build daemon from @var{guix}, and has
@var{build-accounts} user accounts available under @var{builder-group}.
When @var{authorize-hydra-key?} is true, the @code{hydra.gnu.org} public key
provided by @var{guix} is authorized upon activation, meaning that substitutes
from @code{hydra.gnu.org} are used by default.
If @var{use-substitutes?} is false, the daemon is run with
@option{--no-substitutes} (@pxref{Invoking guix-daemon,
@option{--no-substitutes}}).
Finally, @var{extra-options} is a list of additional command-line options
passed to @command{guix-daemon}.
