Scripted applets provided by BusyBox will have been subject to review
on this list and by the maintainers.  We can trust Denys not to accept
substandard scripts just as he does with native code.

Sounds like what Denys was proposing.  To me it seems simpler to keep
the different types of script in different directories.  I don't see
any advantage in putting them all in the same place.

The developer controls what they put in the embed directory.  The presence
(or non-presence) of a script is sufficient to specify whether (or not)
it should be embedded.  I don't see the need for a list.
