--- Comment #11 from desrt <desrt at desrt.ca> ---
So this patch is not right.

I assumed from my reading of the Linux code ("cap_clear()...") that it was
clearing all capabilities of the process when in fact it is only clearing the
"special to root" capabilities.

The FreeBSD version of the code indeed clears _all_ capabilities beyond ones
that the process already has (ie: cannot open any new files, create sockets,
etc.)

This has a pretty obvious adverse effect on pulseaudio's ability to do what it
needs to do -- indeed, it bombs out pretty quickly due to an inability to read
its own config file.

We need to find out if we can drop the special-to-root caps on FreeBSD without
the others.  My initial research into this makes it look like it may not be
possible...
