Since "7d793bf debian: Remove upstart config" --no-restart-on-upgrade
behavior was lost. Add it back with the new name --no-stop-on-upgrade.
Furthermore the install was a mix of the upstream putting files
under /lib and then debian/install putting it under /usr/lib leading
to file-in-root-and-usr warnings.
Furthermore dh_systemd_enable and the formerly dropped dh_installinit
have been consumed into dh_installsystemd for systemd units.
Finally dh_installsystemd will drop the executable bit which is
wrong in the upstream archive and triggers executable-not-elf-or-script.
So overall to hopefully do it right we do:
- ephemeral-disk-warning.service gets installed by d/install
- walinuxagent.service gets installed badly by upstream and removed in
d/rules
- both services are then picked up and configured by dh_installsystemd
