Hi Stefan,

I think this is almost ready to be merged.

There's still one thing I'm unclear about.

I tested it this way:

(1) create ~/config.scm with the following contents:

(use-modules (gnu))

(operating-system
  (timezone "UTC")
  (bootloader
    (bootloader-configuration
      (bootloader grub-efi-netboot-bootloader)
      (target "/boot")))
  (file-systems
    (cons* (file-system
             (mount-point "/")
             (device ":/foo")
             (type "nfs"))
            %base-file-systems))
  (host-name "client1"))

(2) mkdir ~/tf
(3) ./pre-inst-env guix system init ~/config.scm ~/tf

Now, ~/tf contains the system to be booted over the network, right?

But ~/tf/boot/efi/Guix/grub.cfg points to the tftp machine's /boot .
Is that a bug?  Shouldn't it point to the /boot of ~/tf, the system
to be booted?

Likewise, the gnu store directly inside ~/tf is not used, but
~/tf/boot/gnu points to the tftp machines's /gnu.  Shouldn't it
point to the former?

Shouldn't that be

 (string-append mount-point "/boot/grub/grub.cfg")

?

Shouldn't that be

  (symlink-relative (string-append mount-point (%store-prefix)) store-link)

?

Okay.
