In the case of DHCP -- yes, I can.  But sometimes I need to specify
the static entries for the resolv.conf: I am using it when I am
working in some places where DHCP isn't available, so I am creating
branched /etc/rc.conf.  And it is useful to have all variables in
one place.  For my usage, dhclient.conf is not relevant, since I
am happily taking all that was given me via DHCP.

Yes, it is also the way to go, but, at was said by Poul-Henning,
nscd is not so smart to know all particulars of DNS, namely -- the
different TTL values for the different records and zones.

May be I can integrate the usage of the nscd to the dhclient-script
and rc.conf?  Is it desirable?
