Subject: Re: Container Hardening
Jess,
In the vein of your proposal (https://gist.github.com/jessfraz/3a84023ff85471696ee33a20031b9e7b),
there was recently a systemtap (http://sourceware.org/systemtap/) script
written to output some of this data that is not generally accessible
from userspace.
Will Cohen was nice enough to upload this and a quick write-up on it's
usage.

Where this can show when a "badcap" is encountered, or just to see the
profile of capabilities and syscalls used.
