Debian 7 ‘Wheezy’ to introduce multiarch support

“Multiarch is a radical rethinking of the filesystem hierarchy
with respect to library and header paths, to make programs and
libraries of different hardware architectures easily installable in
parallel on the very same system.

“Multiarch is a major enhancement to Debian’s ability to deliver
on the promise of being a universal operating system” explains
Steve Langasek, driving force of the implementation, “not only will
it make crossbuilding easier, but also enables better support for
legacy 32-bit applications on new 64-bit installations and in the
future will even allow live migrations from 32-bit to 64-bit
systems.”
