From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What's DS3231 ?
So far I've only been using ssh to log in to the FreeBSD stick on the pi4, and have been testing it with a GELI encrypted USB disk to explore that and learn some more, besides using LUKS with Linux. I have been thinking about making desktop backups to the Geli disk via rsync. I find it interesting to learn some more internals of BSD again (like years ago). For example in Linux the default command to check your own local IP address is
ip. The commandifconfighas been deprecated on Linux. But on FreeBSD and iirc OpenBSD it is - tada! -ifconfig. I'm curious to have a look at Bastille given enough time.DS3231 is an I2C based high accuracy RTC chip, usually comes in breakout modules. Mine was packaged in such a way you can plug in the header directly to the expansion pins of the Pi.
What you just described sounds wild to me. I'll check it out!
RTC chip, IIRC
