From a high level it looks something like:
- The last couple of bugs with signal handling and init
fixed in the pid namespace
- The uid namespace
If you are someone who can take less than perfection you can build
a better chroot today.
I'm hoping once the current round of changes settles out we
can get a chroot like tool out to people so non-experts can
start using this code.
The short term goal is not to be a Xen replacement but to correctly
implement the namespaces we have and to do something useful. Which
basically amounts to building a better chroot, and to start reducing
the differences between vserver and openVZ.
