| Maybe it's worth disabling cross-namespaces ptracing...

I think so too. Its probably not a serious limitation ?

Several people think we will implement 'namespace entering' through a
ptrace hack, where maybe the admin ptraces the init in a child pidns,

Why not implement namespace entering w/o any hacks? :)

makes it fork, and makes the child execute what it wants (i.e. ps -ef).

You're talking about killing that functionality?

No. We're talking about disabling the things that are not supposed to work at all.
