Hi,

I have found out what happened. Indeed, this issue is that we're not
calling dh_systemd_enable. Or rather, openstack-pkg-tools is generating
the *.service files in the override_dh_installinit target, which happens
after the dh_systemd_enable in the standard dh sequence. So I wrote this:

   # Generate the systemd unit file
   # Note: because dh_systemd_enable is called by the
   # dh sequencer *before* dh_installinit, we have
   # to process it manually.
   for i in `ls debian/*.init.in` ; do \
      pkgos-gen-systemd-unit $$i ; \
      MYSERVICE=`echo $$i | sed 's/debian\///'` ; \
      MYSERVICE=`echo $$MYSERVICE | sed 's/.init.in/.service/'` ; \
      dh_systemd_enable $$MYSERVICE ; \
   done

in the override_dh_installinit. This works, then, except for keystone
where there's no #DEBHELPER# in the postinst (because I wanted to keep
the control of when invoke-rc.d is called, ie after the daemon starts,
the admin tenant is created, and the keystone endpoint is registered).
This means that for Keystone, we need to manually add what
dh_systemd_enable does. Then I've been asking myself what would happen
in Wheezy, and it's looking like the only thing that will happen is that
it's going to add a dependency on init-system-helpers, which IMO is
quite fine, because it's already available from the official
wheezy-backports.

Since the release team already expressed their opinion that fixing
systemd issues the way I proposed was fine, I hope to make it happen
before Jessie is released, with what's currently in the Git for
openstack-pkg-tools (version 20). I would welcome some reviews.

Thoughts anyone?
