I've been using Linux since Slackware. Debian for decades and this is the first time I've heard Debian referred to as 'the universal operating system'.

I guess I just never paid attention to it. My usage of debian goes back thirty years. Like other utterly unimportant facts I am no wiser for having heard it. I pay attention to things that matter.

Much as I like Debian, if it doesn't run on the 3DS then it's not "universal".

Don't know the architecture of 3DS but I remember someone put Debian on a Kindle, so that's universal enough to me. :)
Its Nintendo custom hardware but the CPU is based on ARM11 RISC, so i dont doubt you could get some form of Linux running on it.
First time that I read that line after years in this and many other subs/forums/wikis/news.
