I had a bit of a go at the shell tools side of things.  It was fun in a way, 
but I won't pretend the result was as usable as Plan 9, never mind Linux.  It 
wasn't worth continuing to the point where experimenting with per process 
namespaces might become interesting.  The same goes for making use of Linux's 
interesting clone() system call, which afaik close to rfork().

It was just an exercise.  I wasn't expecting too much out of it because I've 
experimented with minimal Linux before, running LFS from 2001 to 2003 and being 
involved with a source-based Linux distribution from 2004 to about 2009.  My 
conclusion was so much interesting software wants the whole bloatware circus 
that to do without it requires becoming a 1-man patching machine.  This goes 
all the way into the shell.  A surprising lot of software needs the shell to be 
the Bourne shell and the various utilities to have POSIX-specified options and 
behave in POSIX-specified ways.  P9P utilities don't do that.  I also got the 
idea that the days of hobbyist-maintained Linux distributions are over, that it 
takes a lot of dedication or a large team.  I personally resolved to use 
bloatware without paying too much attention to it for "modern" software, and to 
have my fun with what I call 'island systems' -- not existing to provide 
services for modern software but rather little universes in themselves.  They 
can be hosted or emulated, or run on old hardware, I don't care so long as 
they're not going to stop working or break programs I wrote at the drop of a 
hat.  P9P could be considered an island system in itself, old operating systems 
and hardware too, but my current primary choice of island system is Forth.

If, on the other hand, you basically want Plan 9, using Linux as a driver 
layer, there have been multiple attempts over the years, some with corporate or 
academic backing, but none of them seem to have worked out.  The guy behind 
most of them eventually moved on to writing an actual operating system 
influenced by Plan 9.
