Dale,
   Thanks for digging that up. It's interesting, but I don't think
it's exactly relevant. TTBOMK I've used /dev/sdX and /dev/srX for as
long as it's been available. Most of my machines these days were all
built after the change so it's all they've ever known. Maybe one
machine used /dev/dhX.

   However, that's not the issue I'm looking for background on. You
seemed to say earlier that it's a widely known thing that udev links
to /dev/srX are not only broken but also bogus. You don't use them.
Others have seen the same issue. I've seen the udev links not work for
a couple of months.

   However from what I can tell you don't use them
1) because they broke, and
2) like me you never took the time to determine _why_ they broke.

   I was in the same place until yesterday when I decided to dig in a
little bit. Now, my point is that while the old links created in old
rules files are broken (and they are) it's not clear to me that udev
is broken. Clear Kay Sievers (sp?) still assumes they work although
they will automatically only do /dev/sr0. The use is responsible for
creating others if they need them. (Which 99% of folks will not, so
basically, it still works.)

   What appears to have actually broken is the old PCI path
nomeclature, and not 'udev proper', as best I can tell.

   Anyway, it's well known in the known universe that you are mad at
udev so I don't expect you're looking for ways to make this stuff work
and I do appreciate you digging the stuff up that you found. Thanks.

Over and out,
Mark
