@nyanide its barebones. sure you can use generic ethernet drivers to send packets and use the plan9 protocols but anything above that bare minimum is severely lacking
also poor support for any hardware, like most hobbyist systems, its getting by on almost solely limited generic drivers. vga and the like. sure its usable but extremely limited.
its cool to mess with sure and to try and write your own drivers but theres a reason you cant actually use it for as anything remotely approaching a daily driver without severe concessions and virtualization
the only nonposix hobbyist system i can think of not falling into these flaws is haiku but thats because it imports a lot of its driver stack from freebsd
