Correct, I think I got confused by guix-install.sh copying
etc/openrc/guix-daemon to /etc/init.d/guix-daemon. (See the openrc
handler in the $INIT_SYS case statement in sys_enable_guix_daemon()).
Assuming I understand the script; I find shell scripts hard to parse.

I suspect there's a risk. WSL Debian does not come with daemonize out of
the box so I imagine normal Debian does not either.

If OpenRC/systemd does not require daemonize, there's probably a better way to
handle this. Perhaps a INITD_REQUIRE variable that's only checked
conditionally depending on what init system is detected (aka INIT_SYS).
