Implement a quiet prefix, which will disable some diagnostics. The
fast prefix also implies quiet. During boot we use either fast or

An additional benefit of having a quiet prefix is that we can start

Implement the checks for required_* objects as two functions, one
to be run before precmd and the other after it. They get the current
rc command as an argument so they can choose what requirement tests
to perform. As of now, only "start" needs such tests.
Implement a new requirement variable, required_modules. It can
list kernel modules that need to be loaded after start_precmd
indicated success. Each name in the list can be just "file", or
"file:module", or "file~regex". This will allow us to remove a lot
of duplicated code from rc.d scripts.
Perform the checks not only for the default start method, but for
any method. This allows for more flexibility and fixes a few rc.d
scripts (namely newsyslog, pf, sendmail) that rely on a required_*
variable while providing a non-default start method.
To be able to call the new check_required* functions naturally,
remove lots of crufty duplicated code pieces from run_rc_command
and replace each of them by a call to the helper function providing
a single corrected instance of the respective code snippet. Now
run_rc_command isn't as scary as it used to be, and it even appears
to have quite a nice logic that was obscured by the old crufty code.
In the default handler for restart, run start from a subshell to
protect global varibles, e.g., _postcmd, from modification by the
start handler. This enables using restart_postcmd. [x]

Old ramdisk{,-own} scripts will stay a bit in CVS to allow some time for

Two new variables have been introduced to be able to populate the md(4)
