That's one way of doing it, but not the only way.

The current setup doesn't allow for 'stopping' of services.

The 'other' solution works in this case.

The 'other' solution works in this case.

This is *very* much like SysV's init, except that it leaves the system
(ie; standard/normal configuration) localized, and non-standard (custom)
stuff off somewhere else. This si a 'Good Thing' IMHO.
init(8) still needs to be modified to have it run a signle 'shutdown'
script which would do the same thing as above, but it wouldn't be that
hard to do.
The SysV of 'multiple run-levels' is something I've yet to see used.
Even the most hard-core SysV gurus use the two available in BSD,
single-user and multi-user.
