Thanks for reporting this issue.

Indeed, this test does not work as root.
The comment in the test explains that it expects an EPERM error:

   # Ensure that with --ignore-fail-on-non-empty, we still fail, e.g., for 
EPERM.
   # Between 6.11 and 8.31, the following rmdir would mistakenly succeed.
   mkdir -p x/y || framework_failure_
   chmod a-w x || framework_failure_
   returns_ 1 rmdir --ignore-fail-on-non-empty x/y || fail=1

but root does not see the EPERM; strace output:

   ...
   rmdir("x/y")                            = 0
   close(1)                                = 0
   close(2)                                = 0
   exit_group(0)                           = ?
   +++ exited with 0 +++

The attached patch adds guards around the parts of the test which
only work as non-privileged user.

Have a nice day,
Berny


Patch looks good thanks.

An alternative could be to use rmdir itself to test, like:

  if ! rmdir x/y 2>/dev/null; then
    returns_ 1 rmdir --ignore-fail-on-non-empty x/y || fail=1
  fi

cheers,
Pádraig
