I don't have the URL handy, but for example, the ifconfig thing ends up
being translated to the "ip" style (which was added in 2.2 already, I
just recalled), so it goes through additional hoops without exposing the
real interface.
Of course, ifconfig, being mandated by POSIX, will stay around, but it's
by no means the best choice for Linux.

No. The best practice is to not attach a label if you don't need one.

If you so wish. I don't see the point - it'll work perfectly fine
without, and so any script which wants to know all IPs on a system needs
to scan for them _anyway_ already, or is broken.
(ie, fun things issue when you mix IPaddr with IPaddr2, because IPaddr
will miss the IPs assigned using IPaddr2, but not vice-versa. It follows
that IPaddr is broken on Linux and IPaddr2 is not ;-)
Just like you can rename the device itself to any name which pleases
you, and so matching for "eth" for ethernet would be as broken - it's
just another assumption which doesn't hold true.
Sincerely,
Lars
