+2018-12-30  Andrew Ruthven
+  Modify mythtv-update-motd to look to see if /etc/update-motd.d is
+  present, if it is, then generate MOTD content in a compatible fashion.
+  On Debian derived systems we now install a snippet into /etc/update-motd.d
+  to cat the generated file if it is present.

   Fix the output of Next Recording to never have negative numbers.
