Indeed, but I need toysh anyway.

I don't intend to try to convince android to move off of mksh. I just
hope to provide such a drastically _better_ shell that other people do. :)

I expect it to take awhile, and what I really need are regression tests
against every corner case of both bash and mksh...

The downside of which is that if you install toybox over itself on a
system that only has toybox when it does an "rm cp" it then won't have a
cp command in the $PATH to put it back.

(Yes, inadvisable to do at the best of times. And admittedly the current
one would fail with "executable busy" if you try to overwrite a running
file, but it wouldn't leave you hosed either...)

Really I'd like to use the "install" command. It's not posix, but won't
stomp hardlinks.

I'm promoting three of the commands you _are_ using in pending this
release cycle. Trying to get ahead on that...
