a while, but it got a lot longer than I expected :-/
I'd appreciate any feedback and comments!
Thanks Ulrich, that's an excellent document. :)
You didn't mention anything about the HWCAP stuff, though? I think we need to capture the discussion we had about "multiarch" == "ABI", and "multiarch" != "hardware features".
The second half of the section "Loading/running an executable" is about thw HWCAP stuff (look for "capability suffix"). In the summary I have this point:
* If capability-optimized ISA/ABI-compatible library variants are desired, they can be build just as today, only under the (same) multiarch suffix. They could be packaged either within a single pacakge, or else using multiple packages (of the same multiarch type).
If you feel this could be made clearer, I'd appreciate any suggestions :-)
