We can make processes have different namespace by using clone() with CLONE_NEWNS.
But even if some process got a different namespace, it need to follow conventional rules.
Optional files (e.g. /pavlix_config) need not to follow conventional rules.
What I'm talking about is essetial files (e.g. /bin/sh and /etc/passwd).
Can your system continue running even if essetial files are not in place
(like /bin/sh moved to /etc/sh and /etc/passwd moved to /bin/passwd) ?
I don't think so...

Thanks.
