For lack of an answer from someone more experienced, I see two
ways to do this. 

The quick & dirty way would be to call the usual permission and
ownership programs from within Racket.  See
http://docs.racket-lang.org/reference/subprocess.html#(part._.Simple_.Subprocesses)

If you're more ambitious, you can develop a foreign function to
do the job.  See http://docs.racket-lang.org/foreign/
