What do you do about services which have
"start on runlevel [2345]" and the binary is in /usr?

There are quite a few examples here: acpid, atd, cron, irqbalance, etc
which all have:

start on runlevel [2345]
stop on runlevel [!2345]

Either those jobs are buggy to not specify the "start on
(local-)filesystems" dependency or your criteria is not sufficient.

Imho the major problem here is, that there is a mixup between
dependencies that need to be satisfied to be able to run a job and
when (in which runlevels) to start a job.
