Title:
  systemd v232+ journals aren't compatible with journalctrl from 229

Status in systemd package in Ubuntu:
  Won't Fix

Bug description:
  In my attempt to snap gnome-logs, I've run into an issue where gnome-
  logs fails to get the journal when run on an artful host.  The snap is
  built in a xenial chroot against xenial + gnome-3-24 backports PPA.
  The same snap does work when run on a 16.04 host.

  artful has libsystemd0 234 and xenial has libsystemd0 229.  I took a
  stab at building libsystemd0 232 on xenial then build the snap with
  libsystemd0 232.  The resulting snap works fine on 16.04 and 17.10
  hosts.

  To summarize, we need a libsystemd0 built for xenial bundled in the
  gnome-logs snap that is compatible with the running systemd on the
  host.  The basic rebuild of 232 for xenial is compatible with systemd
  from xenial through artful.  But we want to be sure backporting that
  in a supported PPA is not a bad idea.  Ideally we would just cherry
  pick whatever 229 is lacking in our PPA.

  @xnox suggested v232+ journals are built with more features enabled.
