okay, allow me to interject here. Eventually, it seems, we will have
runlevels. Regardless of who wants a feature or not, it will eventually
get shoved down the collective throats of the user community.
Now, if we can do a skeletal runlevel implementation (i.e. we handle things
as we do now: We have a single-user runlevel and multi-user runlevel with
the other levels to be filled in as needed), it probably won't be so bad.
If we can do it *right*. IF. BIG - I say, BIG IF, there.
The thing that offends my visual senses is seeing the Init: changing
state messages, but I think that if it's sufficiently ADJUSTABLE!, then
we can even make them more eye-pleasing (i reserve the right to have
my init report:
Single-user mode. Go away
I'll continue in a minute.

I agree to a point. The point of the skeletal implementation is that you
can then roll your own run-level to get a configuration to the above.
single-user with networking is not necessarily as rare as you might think.
I go there frequently.

No, and yes - see above.

Ah, you said what I did.

IF we do runlevels, and we do them right, we don't have signals going to
init - we have init listening on a loopback unix-domain socket (i.e. it
rejects all calls from anywhere besides 127.0.0.1, although if we wanted
to really get ugly, we could permit it to accept calls from a defined
network or other set of systems, thus allowing remote administration
of init. Yes, this is getting gross, here, but it might be a desired
Now, I don't necessarily embrace what's happened to rc.d. It stinks of
System V, and I don't think this is the right direction to take on this.
But I need to choose my battles, as I don't have a whole lot of energy
to spend on this sort of thing.
The battle I choose in this case is a strong one against the fragmentation
of rc.conf. Loud and Clear: I DON'T WANT TO FIND MYSELF RUNNING SOMETHING
THAT SMELLS LIKE IRIX. It's GROSS. It's NOT well thought-out for the systems
administrator. I don't WANT some stupid script deciding how it's going to
mangle my configuration. Okay, fine, drop it into rc.d, great, fine. But
to have everything split out into different config files? Man, that's
FRUSTRATING, to say the least.
If there are any other dissenters out there, I rather suggest you make
your voices heard! If there are other assenters out there, I'm really
interested in the reasons why splitting rc.conf is a good thing.
I can see a case for making an OVERRIDE somewhere (provided there's a
NOTICE at boot time, i.e., in /etc/rc.conf the line
nfsd=NO nfsd_flags="-tun 4"
and in /etc/rc.d/nfsd.conf
nfsd=YES nfsd_flags="-tun 8"
would produce, at config eval time:
Starting nfs daemons: mountd nfsd@* nfsiod rpc.statd rpc.lockd amd.
*NOTICE: nfsd=YES in /etc/rc.d/nfsd.conf overrides nfsd=NO in /etc/rc.conf
@NOTICE: nfsd_flags in /etc/rc.d/nfsd.conf overrides settings in /etc/rc.conf
Creating runtime link editor directory cache.
Checking quotas: done.
Preserving editor files
But please don't splinter rc.conf.
