# BOF purpose

Cover emdebian current issues, decide 'roadmap', try to leave detailed
cross-compiling stuff to Cross-compiling talk tomorrow, 11am.

# Progress this year

 * grip and crush(for arm) released along with lenny
 * grip being used commercially
 * toolchains building gcc-4.4
 * dpkg-vendor support has been added
 
And progress this week
 
 * auto-building toolchain(s) in debian itself
   * start with x86/amd64 -> arm
 * sh is now dash
 * multiarch changes agreed, including cross-deps.

# Subjects

 * Cross-tools
 * Crush Code audit
 * Crush vs. Grip
 * Debian-variation management

# Crush Code Audit

Examine what we changed for crush and how to avoid changing it there. 
Everyone can get involved.

Install emdebian tools, pick a package, emsource it and see if it works. 
Look if patches can be incorporated into main package 
and/or re-implemented using deb_vendor/dpkg-vendor.

# dpkg-cross
 * cmake support working - needs refining
 * autoconf support - where should it go?
 * transition to multiarch - dpkg-cross going away, but need it during
transition

# cross-tools
 * Uninstalability is a problem - what to do
 * There is now a plan to build them in Debian proper

# Cross-tools dependencies

# Build plan

# multiarch changes things
 * cross-building - OK for debian, not for variants - needs 
   sysroot/chroot
 * dependencies stuff all changes - now install foreign arch stuff
   directly, not convert it to build arch.

# roadmap

 How to order these things?
 
 * Crush Code audit
 * Multiarch toolchain changes
 * Using dpkg-vendor
 * Fixing apt-cross
 
 please dive in - plenty to do :-)
