* Backport from trunk: - Don't lose backup capability when finding out current capabilities. * If PARTMAN_NO_COMMIT is set, then stop parted_server and exit rather than running commit.d and finish.d scripts. Add a new partman-commit script which starts up parted_server again and runs these separately (this also honours PARTMAN_UPDATE_BEFORE_COMMIT rather than PARTMAN_UPDATE_BEFORE_CONFIRM; see changelog entry for 78ubuntu4). This allows Ubiquity to defer the commit stage until after displaying an installation summary to the user without having to leave partman running.
