Fear not. Debian lives on /dev/sda3, guix on /sda1. From Debian
I dit guix system init config.scm /guix

So what I need is for Guix's Grub to create an extra menu entry
for Debian, with this text
menuentry 'Debian GNU/Linux' {
linux /boot/vmlinuz-3.16.0-4-amd64 root=/dev/sda3 ro
initrd /boot/initrd.img-3.16.0-4-amd64
}
When you specify extra an extra menu-entry
(list (menu-entry
(label "debian")
(linux "<file-name>")
(initrd "<file-name>))
then grub.scm:(grub-configuration-file) appends "/" "bzImage" to the
kernel's file-name
(define linux-image-name
(if (string-prefix? "mips" system)
"vmlinuz"
"bzImage"))
So, I setup some symlinks on the Debian side so that I can provide Guix's
Grub wih a kernel file name that can have "/bzImage" appended.

$ ls -l /debian/boot/latest/
totaal 0
lrwxrwxrwx 1 root root 28 6 feb 21:17 bzImage -> /boot/vmlinuz-3.16.0-4-amd64
lrwxrwxrwx 1 root root 31 6 feb 21:17 initrd -> /boot/initrd.img-3.16.0-4-amd64
Possibly we'd want to add another keyword
(linux-image "(hd0,msdos3)/boot/vmlinuz-3.16.0-4-amd64")
that gets used literally?
Greetings, Jan
