* d/src/initscripts/etc/init.d/sendsigs: wait up to 300 extra seconds for upstart jobs that have been killed. They will be sent SIGKILL by upstart when their 'kill timeout' has been reached, so we should trust the job's author to give the service a reasonable amount of time to shut down. (LP: #688541) * also omit pids of stop/killed upstart jobs since we know they've been killed already. * d/src/initscripts/etc/init.d/umountroot: Check for init.upgraded file in /var/run before clearing out /var/run. (LP: #886439)
