When you think of alternatives to Linux, you most likely are thinking of BSD, MacOS, or even Hurd. One such OS that people don’t recommend nearly as often is HaikuOS. HaikuOS is an amazing OS that is based off of the old now defunct BeOS. I am going to go over the instillation, hardware support, desktop, and package availability for HaikuOS.
from what I understand haiku and beOS were UNIX inspired, with some posix compliance, but it’s not a unix-like or unix-based. Kind of like plan9 was.
