Thanks, didn't mean it as a GNU thing at all. Sure, mkdir would've existed
back in research Unix too. My experience has only been limited to the Linux
envs, which is why I was led to attribute mkdir to the evolution in
mknod(), I only know that they all either descended down from SysV or BSD,
those who have used the real Unices would know better. Seeing as I haven't
had the privilege of using any except briefly on an emulator.
