Given I've been a bit quiet on this, I thought I'd better explain
what's going on: I do have these built, but I made the mistake of doing
a dist-upgrade on my testing VM master image and it pulled in a version
of systemd (257.4-3) that has a broken hibernate. Since I upgraded in
place I don't have the old image so I'm spending my time currently
debugging systemd ... normal service will hopefully resume shortly.
Regards,
James
