> test-container-executor.c doesn't work:
> * It assumes that realpath(/bin/ls) will be /bin/ls, whereas it is actually /usr/bin/ls
on many systems.
> * The recursive delete logic in container-executor.c fails -- nftw does the wrong thing
when confronted with directories with the wrong mode (permission bits), leading to an attempt
to run rmdir on a non-empty directory.
