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?<br>

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

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