services: hurd-vm: Disable password-based authentication for root.
With offloading to a childhurd is enabled, allowing password-less root
login in the childhurd to anyone amounts to providing write access to
the host’s store to anyone. Thus, disable password-based root logins in
the childhurd.
* gnu/services/virtualization.scm (%hurd-vm-operating-system): Change
‘permit-root-login’ to 'prohibit-password.
* gnu/tests/virtualization.scm (%childhurd-os): Provide a custom ‘os’
field for ‘hurd-vm-configuration’.
* doc/guix.texi (Virtualization Services): Remove mention of
password-less root login.
