Description of problem:

I configure my eth1 interfaces (on different machines) with DHCP
and I have 'PEERDNS=yes' for good reasons.  Suddenly after
'ifup eth1' my /etc/resolv.conf has a legth 1 with only a newline
character in it.  Obviously many other things are immediately
affected.  That happened after the last series of updates.
This despite of that detail that in /var/lib/dhcp/dhclient-eth1.leases
I still have:


lease {
  interface "eth1";
.......
  option domain-name-servers aaa.bbb.cc.ddd;
  option dhcp-server-identifier aaa.bbb.cc.ddd;
.....
}

which is indeed absolutely correct.

Programs from 'dhclient' package do not seem to responsible
for that trouble as they were installed on "Wed 18 Aug 2004"
(although I would not absolutely swear; I had a number of
other "surprises" recently and possibly missed when the problem
started).

Version-Release number of selected component (if applicable):
initscripts-7.66-1

How reproducible:
