Re: Upcoming Debian multiarch support (amd64, sparc64, s390x, mips64) [affects sarge slightly]

The method of putting libraries into /lib/ and /lib64/ does not work if
you want to have i386 and ppc, for example, on the same system. While
this is not possible at the moment, it will be once someone writes a
good CPU emulator... (or with CLI).
IMO multiarch support could be designed in a way that allows such
future cases to work, too:
. .so files are put into /lib-<arch> or /usr/lib-<arch>.
. /lib/ and /usr/lib are populated with symbolic links to the libraries
for the native architecture by ldconfig;
on amd64 /lib64/ and /usr/lib64/ are used instead and /lib/ and /usr/
lib/ are used for links to leagacy 32 bit libs.
. non-.so-library files (which usually provide the same interface for
calling programs) are kept in /lib/ and /usr/lib/ as usual.
