# Ubuntu's motd is heavily modified and consists of a few basic parts:
# * standard /etc/motd (though it's often a symlink to /run/motd.dynamic,
#   if it's not, it'll be the last part of the motd shown)
# * /run/motd.dynamic which is a cache of the output of running everything
#   in /etc/update-motd.d using `run-parts`. Various packages drop things
#   off in here and the accepted way to disable them is to make them
#   non-executable
# * motd-news - a live-go-get-something-from-the-internet-and-display-
#   it-at-login. This can be disabled in /etc/default/motd-news
