lib64 isn't an RPMism, its a Filesystem Hiarchary Standardism .
Pretty much every distribution but Debian (and derivatives) adopted
lib64 for all platforms where running 32-bit binaries was common place
(read: all platforms but Alpha and Itanium).
Matt Taggart proposed multiarch for Debian in 2004 (where Red Hat and
SUSE already had support for running a mix of 32-bit and 64-bit
applications on one system), which is captured in the Debian wiki .
Ubuntu added support for co-installing 32-bit and 64-bit software in
I'm a bit surprised that Debian and Ubuntu can't continue to have a
symlink for lib64 that points at lib/x86_64-linux-gnu. No matter since
I suppose the correct fix is to install the plugins in /usr/lib/$target/fs
and define FSIMAGE_FSDIR to point there when building libfsimage on
systems that implement multiarch.
