Did you actually properly read his proposal? It actually makes
sense.
What he's saying is what we currently use as bi-arch is not the
way to go. We should not install all libs twice, once as i386
and once as amd64. You only install the amd64 once.
It also says that we don't need to move around all amd64 libs to
the /lib64 dir. Only those for those that we make bi-arch we
should put the i386 lib in /lib and the amd64 one in /lib64. All
other amd64 libs can be in /lib until we feel the need to make it
bi-arch.
What it comes down too is that for all libs in the ia32-libs
package we make an amd64 deb that has both the i386 and amd64
libs in it. This first requires that we have a bi-arch gcc.
Then we can compile all those libs once using -m32 and once using
-m64.
I think this is a much better solution that the ia32-libs too,
since that's just an ugly hack that uses i386 .debs, and you'd
have to wait for fixes in those libs until someone makes a new
ia32-libs package.
I think this is a solution that isn't too much work and can
perfectly work. It should make migration from i386 rather easy,
and even gets rid of the lib64 symlinks.
