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.

If you're in a system where 256mb of RAM is the limit, sure - go for the RAM efficient OS options, they're out there.
Can you even buy less than 2GB of RAM in a desktop system anymore? Even the Raspberry Pi 5 starts at 2GB (and, yes, the older models have less, but I did say desktop system, implying: reasonable desktop performance.) Maybe if you feel the need to use a RasPi 3 as a desktop for something then you should dig around for one of your more efficient OS configurations, but I'll note... back when RasPi 3 was the new model, Raspbian came default without systemd, but offered a systemd option. The systemd option booted from power off to the desktop (such as it was) in about 1/3 the time.
