I have these same warnings all over my syslog in minute-wise intervals

The Linux folks stopped doing it:
2.0 supported the net interface 0.0.0.0 IP address convention (meaning
the kernel should accept all IP pack

Yes, RFC2131 clause 4.1 says:
DHCP messages broadcast by a client prior to that client obtaining

I say with 99% certainty that assigning 0.0.0.0 to
the interface is a requirement of dhcp.
You can't stop using it and expect dhcp to work.

I have seen that situation before as well
and there may be more slight tolerance-style improvements
that could be made but I can't think of any at the moment.

FreeBSD dhclient-script assigns 0.0.0.0 address to the interface in PREINIT
in order to bring interface up. Windows seems to do that as well or
there is no sane explanation for the relatively big number of these nasty
messages I am getting every time MediaOne network goes down and several PCs

I haven't tried this but how about changing the
/sbin/dhclient-script to
The message in question can be extremely useful in case there is IP address
clash on the local network. I suggest we just change the code in question to
ignore clashes over 0.0.0.0 address only.
