Not that you can regenerate the motd by editing motd.template and
running 'service motd restart' rather than rebooting.
Small wordsmithing by me, and updated the example from FreeBSD 2.1.6.1
release to 12.1 release.

Update login(1), its manual pages, similar utilities, and motd.5 to refer to
the new location.
