* Resynchronise with Debian. Remaining changes: - Ubiquity integration: If PARTMAN_NO_COMMIT is set, then exit rather than running commit.d and finish.d scripts; add a partman-commit script; dump extra information to /var/lib/partman/snoop if PARTMAN_SNOOP is set. - Use GPT label by default on Intel Macs. - Use MS-DOS label by default on PS3 systems. * Drop the old PARTMAN_UPDATE_BEFORE_COMMIT hack for Ubiquity; this was only needed for the old advanced partitioner, which won't be supported in Gutsy.
