DHCP clients by default overwrite /etc/resolv.conf to use their own DNS
settings unless you have the resolvconf package installed (which
provides a more principled way to reconcile automatic changes by
creating a whole directory of resolv.conf, one per client, then
creating /etc/resolv.conf as the union of all of those files, and hooks
into all of the programs that have reasons to change /etc/resolv.conf)

If /etc/resolv.conf is a symlink, then the resolvconf package is
installed.
