(Unfortunately that Debian bug initially spoke about two completely
different issues, "Sun RPC" and "GNU Free Documentation License". If you
read it through, you'll see that GFDL-issue was later dropped from that
bug.)
I hope you didn't get mixed up with these two issues.
What Sun's aim was in this matter seems to have been was that a person
would not release work downstream and claim it was Sun's, or derived
from Sun.
My paraphrasing of what Sun is saying goes as follows - "you may use
our work, BUT you _must_ call it your work and cite us as source".
That is standard copyright attribution. It is a real pity that the
words that Sun used are convoluted enough to cause confusion for some
people.
In saying this IANAL, however, I have been using English every day of
my life since I started talking well over forty years ago.
{ ;-) Some would say I was rambling but that is another matter. }
I don't see how "Sun RPC" license could ever be interpreted in that way.
The fact is that if you really feel that you was some kind of
definitive answer you need to ask the right question* of Sun. Neither
Brian nor for that matter myself are unhappy with the interpretation.
We have discussed this in one of our many phone calls.
I considered contacting Sun, but I didn't know what to ask exactly.
The question as far as we are both concerned is answered, questioning
the answer is not a bad thing. However questioning the answer without
sufficient argument is not going to get anyone to rethink a position.
gNewSense has as a project since Brian and I met up to first discuss
it on ICT Expo in the RDS in Dublin Friday 4th May 2006 (nearly two
years ago now), made huge strides, this should not be a sticking point.
A correctly formulated question to be asked of Sun would be:
Providing that people give suitable attribution and include your
licence, do you prohibit the use of your Sun RPC code complete or in
part in other peoples works?
I don't think that is enough. That doesn't handle the issue of
"developed by the user" restriction on distribution.
If I'd know what to ask from Sun, I'd contact them.
