[Bug 1855089] Re: Please show MOTD in containers' shell started without PAM printing MOTD

[Balint Reczey]

** Description changed:

  [Impact]
  
-   * Users of containers may never see the MOTD of the container if they are always to the container's shell without PAM being involved.
-   * MOTD contains important information about the system's health including the security updates to be installed thus it is desired to show MOTD in container shells, too.
-   * The fix is creating a snippet in /etc/profile.d which shows, but not necessarily updates MOTD once a day.

  [Test Case]
  
-  * TODO
+  * Install show-motd in an LXC container.
+  * Observe MOTD shown when starting the container shell with
+    $ lxc shell <container name>
  
  [Regression Potential]
  
-  * TODO
+  * The new functionality is added in a new package, shown-motd, thus users of update-motd should not observe any regression.
+  * The change in update-motd is adding the --show-only optional option. Both the new and old code patch is exercised in autopkgtest and should be safe.
  
  [Other Info]
  
-  * The fix relies on PAM setting MOTD_SHOWN=pam to avoid printing MOTD
+  * The fix relies on PAM setting MOTD_SHOWN=pam to avoid printing MOTD
  twice.
