My habit on the CHWiki is to have the articles on subjects where there is a
lot of documentation online is to have the articles mostly be 'executive
summeries', and corral the links to the stuff online to a section at the end,
so that people who want to see the gory details can look at the original
documentation. See, for example:
https://gunkies.org/wiki/AN/FSQ-7
That works well, even for material that later goes 404, because with the URL,
one can generally find it later in the Internet Archive (things like Google
won't find things that are only there).
Don't ask me to add them, though; I still haven't found time to add the links
to the BSD/OS stuff you found!

Hard Choices (TM), impactful ... whatever, if in the end ones decisions
as CEO aren't profitable for the company, what is one even paid the
big bucks for? Any fool can run a company into the ground.
I was herding HP-UX when Carly Fiorina was evicted from HP and we
had the HP consultants (and our friendly HP field tech) on site at
that time. They told us that the folks back in the HP offices were
apparently literally dancing on the tables and singing "The witch
is dead, the witch is dead!".
Kind regards,
Alex.

Yeah, but Carly Fiorina was _impactful_, man, and that's the most
important thing you can be in this business. When it's a bad idea and
you do it anyway and tons of people complain, that just means you're

"Was" being the operative term here. By the time I wrestled HP-UX for
a living (early 2000s), it was ... not so great. We ran the MCOE (Mission
Critical Operating Environment) package with MC/ServiceGuard clustering
for HA services and paid for the support contract to go with it. Ran
into an issue were something we were trying to do just didn't work and
the kernel told us to take a hike (LVM fun). Fine, time to use that
expensive contract. We had a few rounds of back-and-forth with HP support,
even got IIRC two new versions of the LVM binaries, no dice. After some
time (IIRC at least 4 weeks) they must have found someone who remembered
where the kernel sources were stashed _and_ could read them. We finally
got an answer that TLDRed down to: "What you are trying to do cannot work
because you run into hard coded design limits of the kernel", ok, fair
enough - but why did that have to take so long?
The hardware support (we ran both PA-RISC and Itanium from HP) was an
interesting mixed bag at the time. Our normal hardware support guy was
"old HP" and _really_ good, friendly chap, very competent. So were the
consultants we hired for MC/SG training. Then we got a tech for the tape
library who as originally Compaq and that was just ... bad[0], to the point
where the aforementioned consultants were visibly embarassed and took
over[2].
And from reading between the lines, there seemed to be no love lost
between the two sides at HP at the time ("old HP" and "Compaq acquisition").
Kind regards,
Alex.
[0] Showing up to a (known to the company that sent you) pure HP-UX
environment and demanding that the LTO library be wired to a
Windows server[1] instead because you need to do a firmware update
gets you results that start at loud laughter and move on to
unprintable language.
[1] Aside from us going "WTF?!", that wouldn't have worked anyway since
the Windows servers the other departments had didn't have Fibre Channel
interfaces ...
[2] turns out, one could do the firmware updates from HP-UX if one knew
their stuff

Standard pronounciation I heard was "HP-SUX". And I was HP-UX
sysadmin for a living for a while ..

Coincidentally I just came across a worthwile paper on UBC that
concurs https://www.usenix.org/legacy/publications/library/proceedings/usenix2000/freenix/full_papers/silvers/silvers_html/index.html
Reading between the lines a little bit with the benefit of modern
search capabilities, I can piece together a story in that they ignored
it and then there was a strategic FS shift. In HP-UX 10.x, they
introduce "JFS" (unfortunate name since IBM used it with AIX 3.2 in
1990) which is more accurately a licensed VxFS a.k.a Veritas File
System on top of VxVM. VxFS is interesting in its heyday because it
had many contemporary features like journaling, extents, resizing,
expansion, online defrag, and advanced readahead algorithms and is
supposedly reliable and scalable. It was also empirically very
portable, but I might glean that it was not so delicately ported to
each OS and I see direct evidence it has its own variant of buffer
cache.. which mirrors the ZFS saga. So, after they made that design
decision, it became even more futile and unattainable.
It would be interesting to know if Veritas did a better job with
Solaris, AIX, UnixWare or Windows NT.. a somewhat difficult question
to answer given the sands of time but I will keep an eye on it during
future experiments.

My view of HP radically changed in the late 1980s as the result of
bidding on a contract. I got a call from the marketing person with
whom I was working who was laughing so hysterically that it took a
while to get the story.
It all comes down to the "HP Way".
She went in to pitch our proposal to a room full of guys. A some
point one of them started pounding his fist on the table saying
"No no no no no. You just don't grasp the HP-ness of it." It was
a testament to her skill that she managed to keep a straight face.
That's what it's been to me ever since. The HP-ness.

"Hourly Patches" is one of the names I heard in the small HP-UX shop
in which I worked in the late 1990's. The system updates would
arrive on physical CD-ROM media fairly frequently (or so it seemed
at the time), and those would pile up until somebody applied them.
FWIW, HP's HP-UX tech support at that time was really top-notch, in
sharp contrast to most other tech support with whom I've dealt,
before and since.

I worked with HP for years on joint development. Never heard it called
anything other than H-Pucks.

From what I can tell from the documents I linked, and some other
references, they never ended up doing a UBC.

They didn't understand mmap() semantics at all. The page cache and the
buffer cache both existed, there were races on the coherency and they
didn't share data. So the whole point of mmap(), a window into the
cache, didn't work. If you looked at a file read only with mmap()
and read(), you used 2x the memory you should have because there
were two non-shared caches.
And it was just clunky, I came from SunOS, the bar was pretty high.
Define clunky, you ask? Making stuff work on HP-UX was way harder
than SunOS. Most open source things, you could just type "make"
and it worked. Not so much on hockey pucks.
