IMO, amd64 is appealing to the market precisely because of
its support for 32-bit emulation while the processor is in
64 bit mode.
This is something that the linux guys have gotten all
bolted into place, at least in the kernel--as usual not
all of the distributions agree as to where 32-bit and
64-bit versions of the userland libraries belong.
It's really very disappointing that FreeBSD barely supports
running 32-bit binaries. Moreover it does not support
building 32-bit binaries. The 64-bit is great and all but
there simply aren't the resources for my group to make all
of our applications 64-bit clean.
Incidentially, anyone considering putting amd64 support in
dfly should be aware that when Sun first ported to 64-bit
they stuck with a largely 32-bit userland.
You should also have a definite plan for how to handle the
system having both 32-bit and 64-bit versions of libraries
(including how any packaging system would support this
Maybe the people working on adapting pkgsrc can speak on
just my two cents,
