Comment 9 for bug 814671

it would seem that someone, somewhere is seting up binfmt_misc + qemu-arm-static to be located /usr/bin. I say this given the following:

root@neptune:/bld/developer-cross# chroot ./chroot /bin/bash --login
chroot: failed to run command `/bin/bash': No such file or directory
root@neptune:/bld/developer-cross# ls chroot/bin/
bash ln sleep
...

root@neptune:/bld/developer-cross# cp chroot/exp/qemu-arm
qemu-armeb-static qemu-arm-static
root@neptune:/bld/developer-cross# cp chroot/exp/qemu-arm* chroot/usr/bin/.
root@neptune:/bld/developer-cross# chroot ./chroot /bin/bash --login
root@neptune:/#

And thus it works. I'd been putting qemu-static* into /exp so I could easily delete it from the chroot on cleanup of the rootfs as it was being built.

I haven't seen a way to query where qemu has to be installed in order for apps of that arch to work via binfmt. I'm happy to change live-build3 so that it uses this same hardcoded position, just be nice to have a way to programmatically do the right thing.
