It's definitely not nor has ever been a feature of The One True Unix(tm).
Never saw it on linux, either.

I don't recall that ever being used on Linux - at least from ext2 onwards. I also don't recall ever working on any other Unix that did that either. Perhaps it's a minimal or special-case filesystem option for some OSes?

Clearly, ext3 has moved beyond "packed permission bits" if that ever was a production concept.

Under packed permissions, granting for OTHERS would grant for USER and GROUP too.
Here's my question: When did packed permissions stop being used, if they ever were? Does anyone else remember "chmod o+w foo" silently implying "chmod ugo+w foo" and if so how log ago was that?
