Feren OS, a linux distro focused in customization. Started as a Linux Mint derivative, is now based on Ubuntu and/or Debian (I'm not really sure)
Sabayon Linux. I'm not sure if it's still releasing updates, the main website is dead. It was based on Gentoo and later funtoo, but had a package manager of precompiled binaries. You could still use emerge if you wanted to. Definitely a weird and interesting distro
Blend OS is trying to do the declarative nixos thing but with an arch base. That's pretty cool.
ClearOS was Intel's attempt at an immutable os. From what I remember it was really fast.
Edit: actually it clear Linux not clearOS. Edit: also clear Linux is stateless. I don't know, there's a lot about it I don't understand
I used to run Reborn OS at around 2017 for a few years. It used Cnchi installer, just like Antergos, and when Antergos died, I saw Reborn as its successor. But the title went to Endeavour (why?) and Reborn never got popularity.
One of the coolest distros, ever. It's like a mix of Alpine Linux and Slackware without dangerous firmware payloads.
Of those I'be personally tried, certainly chimera linux or mageia
2 days ago my friend found an old SATA hard drive and gave it to me to check what's on it, and me, not having a disk station or anything, and against all better judgment, I just swapped the disk in my laptop for my friend's, and instead of my laptop being fried it turned out the disk was running something called Crunchbang Linux
Shark Linux
Limiting to those I have used daily and treated as Linux (used the terminal for example) probably Maemo. I used to carry my Nokia Internet Tablet 770, and then my N800 everywhere with me.
Maemo is also an ancestor of both Tizen and Sailfish OS
I see no one has mentioned Bedrock Linux yet. Not sure though how others would rate its 'obscurity' though. It's definitely a standout among distros.
hyperbola
they have a wiki with insane nonsens about why they don't package certain things. Example:
pam
Package has different security-issues and is not oriented on the way of technical emancipation as Hyperbola is trying to adapt lightweight implementations.https://wiki.hyperbola.info/doku.php?id=en:philosophy:incompatible_packages
BOSS.
United Linux - the famous Red Hat Enterprise Linux killer!
Jarro Negro. Made by Mexican students. And as far as I know, it's independent, not based on another distro.
Have you ever heard of arch? That's what I use by the way
Check out the random button on Distrowatch (distrowatch.com/random.php) - it's like a Linux lottery, but you always win something weird!
Smoothwall. I used to run it a lot back in the early 2000s for personal use and even helped set up a couple small businesses with it but I don't hear of anyone else using it these days, people seem to love openwrt and pfsense more.
It was great for just taking any old x86 machine and making a powerful, fully featured firewall/router out of it, including a VPN server, all through a web interface. Nowadays that's boring shit but in 2002 it was pretty cool.
it's main feature is that it completely redefines the system's root directory structure. the only reason i even know it exists is because i'm friends with one of the creators
KISS
it's just a single bash script and a repository containing package definitions to compile them from source.
Basically LFS on drugs.
The first one that came to mind was fli4l (Floppy ISDN for Linux). Originally a distro of German origin that fit on a single floppy disk to turn a 386 or 486 PC into a router for ISDN connections. Last I looked it's still actively worked on.
There are probably tons of more obsuce ones. But this is one I actually used.
Take your pick from the Linux family tree
Well I don’t hear much about Gentoo, Damn Small, Puppy or Knoppix anymore. Wonder if they still exist.
I haven’t done much disto hopping since I settled on Ubuntu around ‘08 and then on NixOS last year. I like my systems working when I need them and waiting around for a new install to finish is boring to me.
most obscure and to me coolest but unfortunately not very active https://sourcemage.org/
Rarely hear about DSL anymore, http://www.damnsmalllinux.org/
Jolicloud. I ran it on an old low-spec netbook in 2013ish, basically a ChromeOS before Chromebooks were a thing. It was discontinued in 2016 but great for the hardware while it lasted.
The old PearOS(which looked like a meme-ish knockoff MacOS), UwUntu and Nyarch
I haven't tried all that many distros, but I'd say Puppy Linux. Pretty neat that it loads into RAM from USB and has fairly light memory requirements, but it does feel a little on the clunky side as far as configuration and stuff goes.
Obscure as in "only for a very specific purpose and nothing else"?...
Well, there is the Mircrosoft linux distro for their azure cloud
I guess DD-WRT as distro for router is also kind of obscure. Or the more general openWRT for embedded systems.
I imagine there was a time when this wasn't obscure, but I'm guessing people today don't remember Caldera OpenLinux. That was the first Linux distro I installed/used. A guy from church gave his copy.
Caldera eventually became SCO. But I'm pretty sure I was using Caldera OpenLinux before the whole Novell patent suit thing.
I created a distro once for class that just had diaspora installed on a live CD. It was only used for demos a looong time ago. DiasporaTest.
I had no idea mageia existed until I met a dude who had it
No one ever mentions Crux Linux
Windows 11
Clear Linux.
