That one's been pretty standard for a while, I think.  There have
been other ways to do it, like putting the ifconfig args into a
file /etc/startif_fxp0 or the like (and that might still work).
Lots of machines get away with ="auto" these days, though,
because lots of home systems run behind neat little nat/router
boxes that run DHCP.  And of course most office systems run DHCP.

That one really shouldn't be necessary in rc.conf, because it's
there in /etc/defaults/rc.conf.  Or should be.

No idea on that one, I'm afraid.  If I had to guess, ... nah,
let's see what it's used for in network.subr...
OK, much as I thought: in the brave new world of ipv6 networking
(whenever that arrives), it's possible to want to "bring up" and
"take down" interfaces from an ipv4 network without interrupting
their connection to an ipv6 network.  So this is new scaffolding
that allows the ipv4 addresses to be split from the rest of the
ifconfig_foo0 line, so that it can be added and removed later.
(All of my systems are 7-STABLE, so it's possible that it does
even less than this on 6.2)

I wouldn't worry about it if I were you.  I never have.

I do remember having to do that at one stage, but not for a long
time.  network_interfaces="auto" from defaults/rc.conf works for
me.

Good luck with it, there.  In my experience, networking is
rapidly becoming more complicated and fiddly as more "user
friendly" features are added to it.  I'm just starting to wonder
how or whether I should integrate the GNU avahi dDNS service into
my existing DJBDNS service (probably not, at this stage)...

Cheers,
