In that case, /hurd could be handled like we handle /run/booted-system .
Rene could use service extension like
(service-extension boot-service-type hurd-boot-gexp)
in order to create the "/hurd" symlink (in hurd-boot-gexp).
That is, if the Hurd can boot that far (until the root filesystem is mounted).
In fact, as a hack, we could create a dummy service that does the service
extension and use it for the Hurd.
