Yes, this was an upstream change (in 1.7.10) after I implemented the
stage1 support. Previously, we installed the systemd .service files
unconditionally, even on non-Linux architectures where systemd won't work.

I'm afraid the stage1 support will continue to be a low priority (and
probably get bugs like this) until it's exercised on a regular basis,
which can't be done in Debian infrastructure until sbuild etc. support
the conditional build-dependencies.

Something like that. Since 1.7.10 we already generate
debian/dbus.install from a generic part and an OS-specific part, because
we don't get Linux-specific systemd stuff on kFreeBSD or Hurd either.
Perhaps the approach I took in that version
(dbus.install-${DEB_HOST_ARCH_OS}) was too speculatively generic, and we
should have been concatenating debian/dbus.install-generic and (in
non-stage1 builds for Linux) debian/dbus.install-systemd; or perhaps we
should have been making use of debhelper 9's support for executable
debhelper config files.

Tested patches welcome :-)

(When testing, please use sbuild/pbuilder/cowbuilder and debdiff to make
sure that when built "normally", the non-stage1 packages end up with the
same files we currently ship.)

Thanks,
