Note that the linux 'capabilities' is not the same thing as 'capabilities'
is to some security researchers. To them a capability is sort of like a
file handle, and you can't do anything with an object until you get a file
handle to it. If you want to give some one else access to something you
have access to, you give them a copy of the file handle you hold. Doing things
this way simplifies some aspects of designing secure systems.
