Subject: [bug#27661] ISO-9660 image working and ready

Thanks!

Pushed.

If we want we can (in the future) provide only the iso9660 image on the homepage (for x86_64).

It will work from CD and USB flash drive - that should cover all the options.

(Usually, ARM systems have a more involved boot process and will not work, neither from SD card nor from CD-ROM - and booting from USB flash drive is out of the question).

Of course it would be nice if people could test the iso9660 image a bit (especially on UEFI systems of which I have none).

To generate one, for example do this:

guix system disk-image -t iso9660 foo.scm # will print the name of the directory that contains "guixsd.iso" in the end.

where foo.scm contains:

(use-modules (gnu))
(use-package-modules linux bootloaders)
(use-service-modules base networking ssh)

(operating-system
  (host-name "beagle-bone-black")
  (timezone "Europe/Zurich")
  (locale "en_US.UTF-8")

  (bootloader (grub-configuration (device "/dev/vda")))
  (kernel linux-libre)

  (file-systems
   (cons
    (file-system
      (mount-point "/")
      (type "iso9660")
      (title 'label)
      (device "gnu-disk-image"))
    %base-file-systems))

  (users
   (cons*
    (user-account
     (name "test")
     (group "users")
     (supplementary-groups '("wheel" "video"))
     (home-directory "/home/test")
     (password "sa5JEXtYx/rm6")) ; Password is pass.
    %base-user-accounts))

  (services
   (cons*
    (dropbear-service)
    (dhcp-client-service)
    %base-services)))
