With that recent post about chrome os not counting as a distro of linux. It does bring a good question, what is a distro of linux?
If Linux is just a kernel then android and chrome os are Linux. Bur no really considers android a distro of linux. So linux is more then a kernel.
KDE say that neon is not a distro but doesn’t really why neon is not but kubuntu is.
It is hard. We had Chimera Linux posted here yesterday, which has no GNU code at all. None of the early Linux distributions had package managers. The best I can tell, “pms” (package management system) written for Bogus Linux in 1993 was the earliest, but package management didn’t hit the mainstream until at least 1995. Slackware didn’t get a package manager until the mid-2000s. But we still all consider them distributions. (Right?)
