* Resynchronise with Debian. Remaining changes: - user-params: Don't propagate vga=*, break=*, *-ubiquity, or noninteractive to installed system. - Use /proc/self/fd/4 rather than /dev/fd/4 in fetch-url-methods/http; the latter doesn't seem to exist in d-i. - list-devices: + New "mmc-partition" type for detecting partitions on MMC devices. + Make sure we also detect platform-omap MMCs. + Don't return entries for extended partitions. - Don't include the battery subsystem on calls to udevadm trigger. - log-output: Always install a no-op SIGCHLD handler, in case the subsidiary process starts a daemon which does not fully disconnect its standard file descriptors. - Use dpkg-buildflags.
