true, it would have been /lib64/ since the hardware doesn't the 64bit extensions for x86. but i think the point still stands that using /lib/ for the new hardfloat ABI is OK rather than needing to go the /libhf/ multilib route. and, if it turns out that we were being too optimistic and we do actually want soft/hard float multilib, i don't think this will be a blocker. as mentioned, the s390x guys have been bad and it hasn't been a blocker for s390/s390x multilib with them :). -mike
