As someone who went through the horror of trying to
de-/etc/netconfig the -lsocket,-lnls stuff in SVR4 while porting a
firewall to UnixWare 2.01 (ick. even getcwd() had an obvious bug in
it), I find I must agree with Chris. Yes, I did have system source.
/etc/nsswitch.conf is okay. Not wonderful, but I can mostly deal
with it. It doesn't list .o files to link in.
[warning: slipperly slope argument comming up. I think NetBSD has
more self-control than that, btw]
It may lead to other things, e.g. /etc/netconfig. Rather than worry
about who has DNS and who doesn't have DNS, etc... why not just make
DNS easier to configure, write "basic.named" to read /etc/hosts and do
away with the rest?
I think Sun has realized this, and wishes to make their "doors" the
way to do most of this. I'd say "doors" are to /etc/nsswitch.conf what
sockets are to TLI. >Best Current Practice<
I am one who rather thought the the method of getting DNS on SunOS
(rebuild the shared library) was the *MOST* elegant solution. I don't
run NIS, no NIS. I do run DNS. Add DNS. It isn't like I need to do
this at runtime. This is where /etc/nsswitch.conf and /etc/netconfig
and even lkm fail: I DO NOT NEED TO DO THIS ON A DAILY BASIS.
SysV with its /etc/conf and idbuild system was very nice. The fact
that it was required and one could not build a "GENERIC" kernel was
bad (idbuild in a firewall? Yuck), but not unreasonable. It's bigged
fault was that you needed a compiler.
