Namespaces in operation, part 4: more on PID namespaces

Parent article: Namespaces in operation, part 4: more on PID namespaces

I wrote a little tool awhile ago to play with this stuff. It's here:

Have fun! If any of you find it useful, let me know -- I can probably polish it a bit and send it to util-linux or something.

Also, on very new kernels (3.8+), a lot of this stuff can be done without privilege if you're willing to accept a few restrictions.

Namespaces in operation, part 4: more on PID namespaces

Integrating these nice utilities in the util-linux is an excellent idea. A few different simple utilities, along with some simple SysV-init scripts (that go in /etc/init.d of ns for convenience) and a generic init suitable for namespace(polished simple_init.c) is all needed to experiment with ns.

Util-Linux already has such tools in git, unshare works with all the name spaces and nsenter let's you create a new process in an existing namespace.

I'm quite looking forward to being able to launch a container in shell.
