I believe we have guarded against exactly this already because libelogind0 conflicts with systemd, so you couldn't change from libsystemd0 to libelogind0 on a systemd install without removing the running systemd (which won't happen). > The concern is there might be other cases where the dependency resolver > gives you an answer that is inappropriate for your environment.

Anyway, I am happy to try to work up a dpkg-divert solution if that is likely to be more acceptable. Thanks. Mark
