commit d04e51d196f0e9c8b11a261fb1574c43575ca234
Author: Jan (janneke) Nieuwenhuizen <janneke@gnu.org>
AuthorDate: Mon Apr 13 17:15:10 2020 +0200

    system: examples: Add bare-hurd.tmpl.
    
    With this, we can now build a VM like so
    
        ./pre-inst-env guix system vm-image --target=i586-pc-gnu --no-grafts \
            gnu/system/examples/bare-hurd.tmpl
    
    it boots, but needs some more setup/services to be really useful.
    
    See also: <https://bugs.gnu.org/40839>; wip-disk-image.
    
    * gnu/system/hurd.scm (%hurd-default-operating-system): New exported 
variable.
    * gnu/system/examples/bare-hurd.tmpl: New file.
    * Makefile.am (EXAMPLES): Add it.
