Ah, yeah, that might be an interesting usecase indeed. But a major disadvantage here is that the FreeBSD Linuxulator can support GUI apps because FreeBSD also uses X11. We don’t (Xlibe doesn’t implement the X11 protocol, only the library). I guess the in-process Wayland server might be of use… but it still sounds like a long shot (given how much effort it appears to be to maintain the Linuxulator on FreeBSD.)
