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.
