Hello, I've now moved this script from the "contrib" directory to /etc/schroot/setup.d/15binfmt (reordered so later scripts can make use of this to e.g. start services and run programs inside). I'd appreciate it if you could possibly give this a check over to make sure it works the way you want. I've put a snapshot at http://people.debian.org/~rleigh/schroot/ which is just a packaged version of the current git repo. It would be good to know if the script is working correctly, and if you're happy with the breaks/suggests for schroot. I've left out all the C++ code previously mentioned in the report, since this script makes it all completely self-configuring, and just gets enabled transparently when needed. We can easily add support for tweakable options if needed; in fact, for this version of schroot, it no longer even requires writing any C++. Many thanks, Roger -- .''`.
