No. Just a straightforward chroot environment with a statically linked qemu in it, and a binfmt_misc config like: e104462:trusty:qemu$ cat /proc/sys/fs/binfmt_misc/qemu-arm enabled interpreter /usr/bin/qemu-arm-static flags: OC offset 0 magic 7f454c4601010100000000000000000002002800 mask ffffffffffffff00fffffffffffffffffeffffff This works fine for the things I try to run in the chroot (mostly test programs, also bash and basic command line utilities). > There are complaints which dists had to solve because QEMU didn't.

I'm sure there are cases which don't work; but we should try to find a way which allows us to make those work (with a recommended change to binfmt misc registration) which doesn't break the old configs in the process. thanks -- PMM
