* Merge with Debian unstable (LP: #404561). Remaining Ubuntu changes: - dh_installudev: Default priority is now 40 by default, the target directory is /lib/udev/rules.d, and rules use '-' as separator instead of '_'. Remove files from /etc/udev/rules.d unless they are user modified; if modified and of default priority, take care to rename. This should eventually go to Debian as well, see Debian #491117.
