* Merge package from Debian experimental. Remaining Ubuntu changes: + debian/control: - Remove mention of using module-assistant; we have a DKMS source package - Add dependency on quilt for our snapshot-date patch - Replace dependency on linux-nouveau-source virtual package. Instead depend directly on nouveau-kernel-source. Version this depends to ensure a compatible kernel ABI (>= 0.0.15). + debian/rules: - Call patch target - Generate snapshot-date in get-orig-source + debian/patches/01_include_snapshot_date - Use snapshot-date included by get-orig-source to define NV_DRIVER_DATE in configure. Helps upstream identify obsolete drivers with Xorg.log + debian/xsfbs/* - Update build-system helper from pkg-xorg. No longer uses deprecated --print-instalation-architecture. (LP: #403316) * Add debian/README.source from quilt package for policy compliance. * New upstream snapshot.
