Hi!

The first thing "someone" asked me when we finally got this amazing service
running and were still pretty excited about it, was

    can we have more than one Childhurd per host?[0]

Sounds like appreciation combined with a valid request, especially since it
implies the intention to setup some serious Hurd build nodes ;-)

Running two Childhurd instances on my laptop right now, using this
configuration

--8<---------------cut here---------------start------------->8---
      (service hurd-vm-service-type
               (hurd-vm-configuration
                (disk-size (* 5000 (expt 2 20))) ;5G
                (memory-size 1024)))

      (service hurd-vm-service-type
               (hurd-vm-configuration
                (os (operating-system
                      (inherit %hurd-vm-operating-system)
                      (host-name "childhurd1")))
                (id 1)))
--8<---------------cut here---------------end--------------->8---

look:

--8<---------------cut here---------------start------------->8---
$ sudo herd status | grep hurd
 + hurd-vm
 + hurd-vm1
11:10:46 janneke@dundal:~/src/guix/master [env]
$ ssh childhurd 'hostname; df --si / 2>/dev/null | tail -1'
childhurd
-               5.3G  934M  4.1G  19% /
11:11:00 janneke@dundal:~/src/guix/master [env]
$ ssh childhurd1 'hostname; df --si / 2>/dev/null | tail -1'
childhurd1
-               1.3G  894M  272M  77% /
--8<---------------cut here---------------end--------------->8---

Greetings,
Janneke
