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.

I'm not saying it can't happen, but I've been using Linux since the late 90s and have never had a problem with an incomplete write damaging the file system, or really anything else (except for a recent incident when a new motherboard decided to overwrite the partition tables on my RAID5 array, but that's a different story). And I have UPSs on the server and desktop, and of course the laptop has a battery in it, so the risk of sudden power loss is extremely low.
The /tmp thing in RAM is interesting. I was reconfiguring my server's drive the other day, because I didn't originally allocate enough space to /var - it worked fine for years until I started playing with plex, jellyfin, and Home Assistant (the latter due to the database size). I was shocked to find /tmp only had a few files in it, after running for years. I think I switched the server to Debian in 2018 or 2019, but that's just a guess based on the file dates I'm seeing. Maybe Debian cleans the /tmp partition regularly.
