Lets be clear, re-running the do_install task *is* supported and works
today. It is actually meant to work when re-run. do_install clears out
${D} at its start so we can assume in do_install functions that it is
empty at the start of the function.

The only problem may be if you're manually re-running the do_install
script in WORKDIR/temp. If you're doing that, you have other problems
like the missing fakeroot environment to handle so the non-empty
directory is only one minor issue, you're missing other setup pieces as
well.

Cheers,

Richard
