I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the

directly to me, rather than to the whole list.)
Now that Novell has definitively been found by the courts to own the
Unix copyrights AND decided not to sell them in their latest batch of
financial flailing about, I'm wondering what they're going to do about
the Ancient Unix license. While they've promised not to sue anybody
about Unix, I'm wondering if they'll ever officially endorse the
Ancient Unix 4-clause license or perhaps even switch it to something a
little less awkward like a 3-clause BSD clone or the MIT license.
Also, I wonder if perhaps they might be convinced to expand the
license to cover things like System III or maybe even some early
versions of System V. How might one go about making these inquiries?

New awk existed inside the Research group for some time before it
filtered out through System V. It was even available separately,
directly from them, to educational institutions. Circa 1986 I got
a copy that way when I worked at the Emory University computing center.

True but not relevant; new awk was released with System V at either
3.1 or 3.2; I'm leaning towards 3.1 since that is what I wrote way back
when in the gawk manual when I knew for sure. :-)
Unless anyone can check the actual sources, I think we should declare
this closed... Thanks to everyone for the feedback.

quote of Aho from an interview ---
"We [Aho and Kernighan] had created a grammatical specification for AWK but
hadn't yet created the full run-time environment. Weinberger came along
and said 'hey, this looks like a language I could use myself', and within
a week he created a working run time for AWK."
I know for sure that in 1988's svr3.2 the "awk" command was the 1988 version
and the "oawk" command was the version from 1979.
In svr3.0 the "awk" command was the old and we'd get the new one
from Holmdel's unix tools distribution group (called USTOP) and
install it as "nawk"
I think you could get the new one in stock svr3.1 but cannot
remember it it was provide as "awk" or "nawk."

Regardless of its technical merits (and I suspect that the implementation may have been pretty bad) RFS was doomed by AT&T's licensing policies and general ineptitude at marketing UNIX. Similarly the widespread adoption of NFS was driven by the fact that Sun made it a de facto standard.

PJ from groklaw.net has asked me to trace the origin of
the errno names and values in recent versions of Linux. Attached
is where I am up to. The columns are:
- errno name
- errno value in Linux, and its original value if different
- system which originally defined it
- release date of that system
There are a few errno names which I don't think I have the
correct original system:
EDOTDOT, ENOMEDIUM, EMEDIUMTYPE, ECANCELED,
ENOKEY, EKEYEXPIRED, EKEYREVOKED, EKEYREJECTED,
EOWNERDEAD, ENOTRECOVERABLE, ERFKILL
Can anybody shed some light on these ones, that would be
great, especially if they come from SysV or Unixware.
Also, if you can spot any other mistakes, let me know!
Many thanks in advance,
