it actually is a 'namespace' thingy, so what you
want to do is enter _all_ namespaces and list their
view of the virtual filesystem layer ...

unfortunately mainline does not provide a simple way
to do so, but fortunately you can get away most of
the time by using vnamespace ...

a generic context loop in bash looks like this:

 for n in `cd /proc/virtual && ls -d [1-9]*`; do echo $n; done

to enter a namespace use something like this:

 vnamespace -e <xid> -- <command> [<arg> ...]
