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 have been wondering about this. People recommend backing up
/homeand then reinstalling very casually, eg many recommend a new install when the new Debian stable is released every two years. My personal files and most of my user setup are stored in/homebut wouldn't many customisations be stored in/? I have been tweaking things for nearly a year to get everything working. I wouldn't want to spend ages to reinstall applications (flatpaks and all) and re-create my working setup. People being so relaxed about nuking their setup tells me I may be missing something here.Yeah there's a fair bit outside of home people don't mention. Basically any system-level stuff: fstab mounts, all your system packages, /opt installs, config tweaks you had to do. It tales some time to get set back up after a while on the same install.
After having to reinstall a couple times myself I now don't touch anything outside of /home by hand. It's all scripted so that I can copy /home, run the script, and be back up and running. Well, theoretically, there's usually a hiccup or two. But the peace of mind knowing it's all (self) documenting is quite nice. Not for everybody of course.
your customizations should usually go in /etc and /usr/local so you could back those up. your distro ought to have a guide on backing up your package selection. but yeah i don't enjoy wiping everything and starting over
ah, OK it's not just me then. I find the prospect of having to reinstall Debian on my main work machine every two years is scary. I'd rather have the messy partitioning for the rest of my life :)
Why? Upgrading is pretty straightforward: it's a matter of editing a single text file.
if it helps i've been using the same install of gentoo since 2007. the hard drives, cpu, ram, init system, and everything else changed but it's still that same install. or is it? vsauce music
Very reassuring. The Ship of Theseus approach has been working for me for decades.
Honestly, those who reinstall constantly feel like people that don't take care of their stuff as they should. There's no need to reinstall.
I've been thinking of reinstalling my endeavourOS install to arch just because at the point I'm at, it's basically arch, but the system print shows endeavour, and low key pisses me off. It's such an incredibly stupid reason to reinstall, I want everything just like I have it currently, but changing the files so they think the system is arch sounds... Something I definitely shouldn't do. Dammit.
I'd take that with a pinch of salt. Over years, systems can get quite crufty and by my own experience, things like GNOME can break from upgrades even under Debian. A reinstall can tidy things up.
