** Description changed:

- systemd v232+ journals aren't compatible with journalctrl from 229
+ 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.
  
- This normally isn't a problem, but in trying to create a snap for gnome-
- logs I've run into a situation where we need to build the snap for 16.04
- which has libsystemd0=229.  This snap works fine if the host is running
- 16.04 as well.  But on an artful host, the snap fails to access the
- journal.  I've tested backporting v232 from zesty to xenial and building
- my snap with libsystem0 232.  This works fine on 16.04 and 17.10 hosts.
+ 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.
