Sorry I'm only getting to this thread now :/

I'd like to try and summarize the interrelated packaging changes that were
mentioned in this thread:

- The iso layout is not optimal for programmatic consumption
- The iso layout is not compatible with windows driver media autodetect
conventions
- The iso and RPM host contents do not match
- The reasoning behind the iso/RPM layout is not clear

To all this I say... preach, my brother :)

The ISO and RPM layout is largely the result of organic extensions and no one
ever tried to streamline things, so I fully support any work in that
direction. But the things to consider:

- There are many consumers of the iso layout as it is right now. Any changes
in the short to medium term need to be entirely additive so we can get the new
layout right without breaking every consumer. So keep the existing iso layout
of $drivername/$weird-os/$arch, but _add_ the $arch/$standard-os/* layout, and
avoid duplicates by hardlinking identical files (the scripts on github already
have code that handles the last bit). In fact it might be a good starting
point to write a script that takes the existing iso, extracts it, and
rearranges the contents to match the new format. Then I could help integrate
that with the scripts and my own testing.

- The layout should use the latest windows conventions for arch/osname. If
this means we have to diverge from the naming convention we currently use for
RPM host installed drivers, that's fine, since we can maintain back compat
there with symlinks. However I've tried searching for this info (googling
'windows driver cd layout/hierarchy/format') but I can't find anything
definitive... anyone have a pointer? Especially WRT the current standard vs.
the pre-windows-7 standard that vadim pointed out.

- Anything regarding a separate iso with a separate layout to appease < win7
windows vintage should be handled separately, if at all IMO

Let's stick with email and virt-tools-list redhat com since there may be lots
of discussion...

Thanks,
