05/28: system: hurd: Remove qemu networking from %base-services/hurd.

[guix-commits]

janneke pushed a commit to branch hurd-team
in repository guix.

commit 31563aff635d848ced223882a61e0b691f667730
Author: Janneke Nieuwenhuizen <janneke@gnu.org>
AuthorDate: Sun Oct 20 19:37:25 2024 +0200

    system: hurd: Remove qemu networking from %base-services/hurd.
    
    This allows us to use %base-services/hurd for services in a Hurd config for 
a
    real machine without removing static-networking.
    
    * gnu/system/hurd.scm (%base-services/hurd): Factor networking out to...
    (%base-services+qemu-networking/hurd): ..this new variable.
    * gnu/system/examples/bare-hurd.tmpl (%hurd-os): Use it.
    * gnu/services/virtualization.scm (%hurd-vm-operating-system): Use it.
    * gnu/system/images/hurd.scm (hurd-barebones-os): Use it.  Add comment about
    QEMU and networking for a real machine.
