linux'c `clone()' syscall (the underpinnings of fork()) actually do accept
CLONE_NEWNS, CLONE_NEWNET, CLONE_VM and other flags, pretty close to p9's.
there's also chroot() that moves an inch into the right direction.

however, due to security reasons (the SUID bit comes to mind, but must be
other ones too), all that -- and mount() and mount(MS_BIND, ...) -- are
restricted to superuser only; what a shame

maybe it is be possible to create a SUID-less Linux distro, based on factotum
perhaps, that'd allow everybody access to those syscalls and options.

afaik, x11 is considered an afterthought, bolted onto POSIX systems, and thus
not integrated all that well. you can take a `screenshot' of textual console
with the `cat' command, FWIW.
