** Summary changed: - dhclient is not stopped during shutdown + /etc/init.d/umountroot: "mount: / is busy" due to dhclient is not stopped
** Description changed: The result is "mount: / is busy" and root filesystem recovery during next boot. network-manager 0.9.8.0-0ubuntu3 in Raring neither stop dhclient in response to "stop network-manager" nor remove pid file from /run/sendsigs.omit.d/ So dhclient skipped by /etc/init.d/sendsigs and a lease file is open for writing in /var/lib/NetworkManager while /etc/init.d/umountroot is running. As a consequence root filesystem can not be cleanly remount readonly before poweroff. In default setup the problem is hidden by plymouth. The problem does not appear if network is disabled or the cable is unplugged before shutdown.
