right way to shutdown services

[Alex Efros <powerman@powerman.asdfGroup.com>]

Hi!

I notice Pape recommend this to shutdown services:

    sv -w196 force-stop /var/service/*	    # TERM, pause, KILL
    sv exit /var/service/*		    # TERM, TERM to log, exit runsv

but it's unclear for me is it better than this:

    killall -HUP runsvdir
    killall -TERM runsv			    # TERM, TERM to log, exit runsv
    svwaitdown -t7 /var/service/*	    # pause
    # ... and some time later:
    killall5 -9				    # KILL

Pape's way may be better from this view: if ./run don't exit after TERM,
then it will be KILL'ed and __then__ TERM will be sent to ./log/run.
In my way ./log/run will be KILL'ed together with ./run and will've no
chance to exit gracefully on TERM. But... is it important, especially in
case we anyway forced to KILL ./run?

My way has another feature: it will try to gracefully shutdown
runsvdir/runsv processes which other, non-root users may run. There no
way to know which directory these users supervise with runsvdir, so I
unable to run 'sv exit /path/to/their/dir', but I still can HUP _all_
runsvdir and TERM (exit) _all_ runsv - this give their services chance
to exit gracefully on system shutdown.

To have both features probably enough to add '-k' option to my svwaitdown..?
