Re: configuration files

    We already have start/stop/restart/rcvar support though quite a few
    of the RCNG files only support 'start'.

    You know, it occurs to me that we could augment RCNG to record subsystem
    status in the kernel environment and write a little shell script for
    /sbin which allows you to issue start/stop/restart/rcvar commands for
    particular RCNG files (rather then have to type 'cd /etc/rc.d; sh ./blah
    stop').  

    e.g. something like this:

    rcng start <blah>		Start entity
    rcng stop <blah>		Stop entity
    rcng restart <blah>		Restart entity
    rcng rcvar <blah>		List rcvars associated with entity
    rcng list			List all entities and their current run status

    So for example:

    rcng sendmail restart

    In fact, I think this would be extremely useful, and so easy that I think
    I can work it up in an hour or two with only minor changes to the kernel
    to support kenv -w var=blah to record the current subsystem status.
