No exit here.
Still it dies.

Not everyone has ipv6 yet.
Also the implementation might differ from place to place.
My experience was first with the wide-dhcp (no script, just simple
hacks), now it is isc dhclient as it is distributed with Fedora.
Need to patch dhclient to work with ppp (!) and to patch dhclient-script
to make it work with prefix delegation.
So if we don't use ppp but still use isc dhclient we might see this
issue in more places as dhclient-script fills resolv.conf with the input
from the dhcp-server(s).

So yes, the problem is possible but not too often...
