We should document that to prevent /lib64 to be used for wrong purpose. > In any case I'm not quite sure whether shipping files in lib64 in amd64 > packages (juffed/juffed-dev and zynaddsubfx-dssi do this now) is OK. I only found zynaddsubfx-dssi: /usr/lib64/dssi/libzynaddsubfx_dssi.so which I think is a RC bug. But note that this bug is about /lib64, not /usr/lib64 Cheers, -- Bill. <ballo...@debian.org> Imagine a large red swirl here. -- To UNSUBSCRIBE, email to debian-policy-requ...@lists.debian.org with a subject of "unsubscribe".
