Clear Linux.
elive
you think a distribution that automatically includes all the proprietary stuff that we use baked into the distro would be more popular since it makes linux ready to go for most people; but it still gets fewer than 300 clicks per month.
Its unpopularity may be related to that it asks money or a positive review in a blog to even try. Used to be so a few years ago.
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.
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.
most obscure and to me coolest but unfortunately not very active https://sourcemage.org/
I remember reading about it like 10 years ago along with LunarLinux (e: and sorcerer) as was curious about other source based linux distros. I thought both were dead, glad that at least sourcemage is still alive
