You can’t tell directly from the commit message, but committing to DragonFly may trigger a reminder to MFC, based on commit message content. This is thanks to Aaron LI. It’s little, but this sort of automation is a good idea.
So, if you find yourself in possession of an ADM-3A terminal, and want to attach it to a DragonFly machine, here is the /etc/ttys config (viewed on the ADM-3A itself of course) and the front switch settings that worked for me.
This won’t affect your day-to-day operation of DragonFly, but it’s interesting: apparently, uptime was always (now minus boot time). If you reset the clock on the machine, however, it would no longer be accurate. Now it is accurate, for a number of utilties.
