this problem still exists under 9-current.
the following test app:
#include <sys/stat.h>
#include <errno.h>
#include <stdio.h>
#include <unistd.h>
main() {
rmdir("/");
printf("rmdir errno: %d\n", errno);
mkdir("/", 511);
printf("mkdir errno: %d\n", errno);
}
produces this output:
rmdir errno: 21
mkdir errno: 21
which is EISDIR (as reported by Andreas Fuchs).
could somebody please check if the attached patch is sufficient to solve this
problem? with the patch the test app now outputs:
rmdir errno: 16
mkdir errno: 17
16 being EBUSY and 17 being EEXIST. this is what Andreas Fuchs suggested.
cheers.
alex
