I got sick of Mac developers pointing out that Linux doesn’t have anything like their “Universal Binaries,” so I did something about it.
Comments welcome. I’m submitting the kernel patches later today when I figure out how to do it without looking like a n00b, but feel free to play with it. There’s even a whole proof-of-concept virtual machine, with Ubuntu 9.04 x86 and amd64 installs glued into one.
Developers, post your comments!
