Since this script is not part of the _data_ for nodeinfo test, I'd rather put it in the tests/ directory. But I don't have a strict preference.

I'm not sure why typeset is better then (or compatible as): name="$1" and somewhere the parameters naming almost doubles the function length, but this is just a support script and not something we call on all machines, so I'm OK with keeping these as they are.

If there are errors we don't care about, why don't you just copy the files that match wither KEEP_LINKS or KEEP_DIRECTORIES? You can check that all of them copied correctly and you don't need to redirect the output, so any possible error gives a clue on what's wrong.
