Comment # 5 on bug 1133929 from Thorsten Kukuk

I like this, as it fits perfectly well with 
https://github.com/thkukuk/atomic-updates_and_etc/blob/master/README.md

It should be no problem to enhance pam_motd to use /usr/share/misc/motd, too,
and we should do that: else ssh e.g. could not display the file.
