There is at least one more cause of busy / besides network-manager

I have noticed file /var/log/upstart/ureadahead-other.log opened
for writing by init when /etc/init.d/umountroot was running.
It seems that the problem was caused by absent pack file
in /var/lib/ureadahead/ for a partition added some time
after installation.
I can not find config responsible for presence of
/sys/kernel/debug/tracing/events/fs
required for ureadahead.
I am in doubt if "stop on" condition is intentionally missed
in /etc/init/ureadahead-other.conf
I do not like ureadahead-other status
# initctl status ureadahead-other
ureadahead-other start/running, process 811
# ps uw 811
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

(no process 811)
