No-one (well not me anyway) is proposing that NetBSD emulate SysV.
You're right, SysV is painful to manage, and that isn't where I would
like to go. But the way that all of this is done on SusV is nothing
like what is suggested, there the decision is made by a combination
of linking the startup script to a weirdly named file in another directory,
and then by arranging for the system to enter a particular run level.
I certainly hope that isn't what I have been suggesting.

You're right, I have no authority in NetBSD at all. You can take some
heart at that if you like (that is, it isn't likely, or even possible,
for me to make this change). I haven't had time to do as much NetBSD
development work as I'd like. One day maybe. But even if that happens
I won't be included in the list of contributers, I prefer to avoid
such noise as much as possible.

rc.conf is an OS config file? My OS config file, last time I looked,
was in /sys/arch/`uname -m`/conf/NAME
Or is it that you're saying that syslog, cron, named, ntp, sendmail,
xdm, gated ... are all "part of the OS" ?
And if so, why aren't you wanting their config files to be merged into
rc.conf ? They all have separate config files that you have to manage
separately from rc.conf, and they're all also listed in rc.conf as well.
| That's your opinion. Stop stating your opinions as fact.
Yes, of course, it is all my opinion. What you write is your opinion.
This is an area where everything is opinion...

sudo to run any reasonable editor on a root owned file is equlivaent

And it isn't an issue of trust, it is an issue of avoiding mistakes.
Even if it was reasonable to let people edit the combinaed rc.conf
file, I would prefer not to - it is too easy there for someone to
accidentally break something which they dn't really understand,
And last, for most of the NetBSD systems around here, no administrator
ever goes near them directly, the systems update themselves based
upon scripts installed by admins on servers that the client systems
just run as they're needed. And I can assure you that it is much easier,
and breaks far less often, when the update script does
cp proto-file /path/to/dest
than when it attempts to edit a common config file (and you can treat
that as fact or opinion as youlike).

The "defined format" for rc.conf is that it's a shell script that
contains only variable settings and comments. Aside from that, it
looks as if almost anything goes, just consider this fragment...
# NFS daemons and parameters
nfs_client=NO # enable client daemons
nfs_server=NO # enable server daemons
amd=NO amd_flags="-l syslog -x error,noinfo,nostats"
amd_dir=/amd # mount dir
amd_master=/etc/amd/master # master map
While I guess you could write something that can figure out what is
going on there, parse it, and re-create it, I think I'd prefer not
to have to.
And while I could write a dedicated application which knows that for
the NFS server, as well as "nfs_server" there's also "nfsd_flags"
(not "nfs_server_flags" as the general rule would imply) but also
"mountd_flags" to be set, I think it would be nicer for everyone for
a general application to simply be able to read an option script, and
allow the user the option to set all of the variables defined in the
script when they come to ask to "config nfsd" (or nfs_server, whichever
it is to be)
And all this is ignoring the possibility of actually allowing both
options to continue to exist - letting you keep all your settings in
rc.conf if you like, but also allowing them to be in individual files.
And even the latter is "all in one place" really for those who claim
that is what they need - it's just that the "place" is a directory
rather than a file.
