It's fine.

I applied this a day or two back, although my email's still a bit  
screwy so I'm only replying to the mailing list post now. :)

Possibly we should just have a numeric unshare flag you can specify in  
hex on the command line, then they could do what they liked without us  
arbitrarily assigning letters to stuff...

Eventually I'd like a much simpler lxc replacement to be part of  
toybox. Something that can do a sort of "chroot with extreme prejudice"  
to set up a container, feed it network devices that route to the  
outside world, handle console I/O, let the host get a process list for  
the container, etc.

Haven't done the design work to see what that would look like, though.  
Vague ideas, not enough details to actually start coding.
