My OS config includes a reference to 'upower-service', which is now
deprecated, but the deprecation message is bogus:
mhw@jojen ~$ guix system build /etc/config.scm --verbosity=1
/etc/config.scm:149:19: warning: 'slim-service' is deprecated, use
'slim-service-type' instead
/etc/config.scm:156:19: warning: 'upower-service' is deprecated, use 'Return
a service that runs @uref{http://upower.freedesktop.org/,
@command{upowerd}}, a system-wide monitor for power consumption and battery
levels, with the given configuration settings. It implements the
@code{org.freedesktop.UPower} D-Bus interface, and is notably used by GNOME.'
