I detected the following problem: Ex. # sandboxshell [s]foo# addpredict /usr/bin [s]foo# touch /usr/bin/xxx touch: cannot touch `/usr/bin/xxx': Permission denied I thought, because of "addpredict /usr/bin", "touch /usr/bin/xxx" should not create "/usr/bin/xxx" but I also supposed no error should be issued! Only a log output.
it did work correctly from the sandbox pov, but `touch` does a lot more work such that it detects an error happened with creating /usr/bin/xxx
