An already available option would be to override the grub-installer like
this :

--8<---------------cut here---------------start------------->8---
(define no-op-installer
  #~(lambda (bootloader device mount)
      (display "no op")))

(bootloader (bootloader
             (inherit grub-bootloader)
             (installer no-op-installer))
--8<---------------cut here---------------end--------------->8---

I admit this is not ideal, so I would propose two options :

* Allow for target field to be #f and do not call the installer when
this happends.
* Precise the --no-bootloader parameter of guix system to deal with
multiple cases, for example :

--bootloader=[default|no-config-file|no-install|...]

WDYT ?
