I'm not sure if I understand your question. An interpreter will need a
(read-only) capability to the script it's supposed to execute. Further, it
just receives extra capabilities (for a (possibly private) file system, for
example) just like any other process does. If it's a POSIX process (so it
doesn't know about capabilities), then this is done by the POSIX layer (I
think of it as a library, but it may end up to be something else), which
probably passes them on as files which can be opened or so.
Does that answer your question?
