 I've asked Colin about this, and he implemented support for that in
 trunk!  :-)   (I tested it, there was an issue in the original version
 but r109 fixed it)

 (bzr+ssh://bzr.debian.org/bzr/binfmt-support/trunk or
 http://bzr.debian.org/binfmt-support/trunk)

    % sudo apt-get build-dep binfmt-support
    % ./configure && make
    % src/update-binfmts --find $chroot/bin/true
    /usr/bin/qemu-arm-static

 Note that the --find might return multiple interpreters; in this case,
 the kernel tries them one by one.

 Perhaps we should do something like find the first static interpreter,
 or always copy the first interpreter and warn if there is more than
 one?

   Cheers,
