in repository guix.

commit 32003be074676093cd204405d24d7bf3502e8c09
Author: Janneke Nieuwenhuizen <janneke@gnu.org>

    services: childhurd: Bump default qemu memory to 2048MB.
    
    When booting with pci-arbiter and rumpdisk and using 1024MB of memory for
    qemu, booting hangs, or seems to hang, at the end of the rumpdisk boot
    messages.  At least 1200MB is required, currently.
    
    * gnu/services/virtualization.scm (<hurd-vm-configuration>)[memory-size]: 
Bump
    to 2048.
    * gnu/system/examples/bare-hurd.tmpl: Suggest using 2048 here too.  Update
    example `guix system image' and "qemu" command lines too.
