This time I wanted the AMD64 ISOs more optimized and the Haswell is AVX2,
and as this was too much for some folks I rebuild a second one with just AVX.

Yes, that leaves out first gen x86-64. Historically I always built generic,
“Athlon64”, however, given the nature of “optimizing source distribution”,
I wanted some extra performance to better compete with Intel Clear Linux ;-)

Yes Intel SandyBridge and AMD Jaguar and later IIRC.

Given the confusion, Maybe I have to resort to just build generic Athlon64 /
Core 2 ISOs in the future to just work everywhere.

Ideally i would JIT my whole OS, but that is another story, …
