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. > One major difference is X11.
