Um, you mean "after a new install", then? Would I therefore be correct in
inferring that what's is in place from a 4.5-REL[-pN] install (specifically,
/etc/rc.conf [en|dis]abling whatever is in /etc/defaults/rc.conf) will
actually result in the same runtime after an upgrade to 4.6-REL?

We-ell, to be fair, I think the heat is due to lack of light... I don't
recall a "Best Practices" coming from you, or anyone, regarding rc.conf.
Worded differently, I certainly don't recall anyone saying /etc/rc.conf
should be an edited-down copy of /etc/defaults/rc.conf that guarantees
what is up and down; not until yesterday, anyway.
What I've seen has always stated that what's in /etc/rc.conf overrides
what's in /etc/defaults/rc.conf; by changing the latter, you certainly
may change someone's actual runtime, and that's one of (the last of,
now) the things that bothers me. You've blown POLA out of the water, and
without blatant warning or notification at the right time, that someone
is gonna get hurt.
Have I missed a reassurance somewhere?
Dave
