Cockpit motd support

hi, Cockpit 169 (released today) contains a change to take advantage of the recently added PAM support for /etc/motd.d to display a helpful note to the admin about how to start or access cockpit. The required PAM changes have already landed in Fedora 28. It seems that the PAM configuration of Fedora 28 (at least in our test images here) doesn't use pam_motd at all, though. I'd like to start a discussion about what would be appropriate here. We want at least a message displayed when people log in to an interactive session with ssh, but it might also be useful to display a message at the virtual console, before or after login. Thoughts? Thanks in advance, Allison
