This is your regularly scheduled and apparently necessary reminder that SteamOS is Linux.

SteamOS is built from Arch Linux.

The Steam Deck runs Linux. So will the Steam Machine and Steam Frame.

@gamingonlinux i will accept that when a "normie" can download & install it on their generic x86 system just like any other "Linux" distro. Till then to me it is not much more Linux than Oracle Linux is. Any corporation that uses Linux to lockdown to their ecosystem isn't doing that out of goodness of their heart or what is best to consumers but to maximise their return to shareholders.
@htpcnz @gamingonlinux It's not locked down tho? It just doesn't have driver support for desktop hardware, and why would it when it's designed to be a handheld OS?
