nfsd daemon doesn't work anymore
================================
The RedHat distribution 2.x and 3.x have a bug that they do
route add -net 127.0.0.1 at startup. That is wrong. Correct is
route add -net 127.0.0.0.
The Red Hat distributions 2.x, 3.x and Caldera 1.0 have a bug where
they do "route add -net 127.0.0.1" at startup. That is wrong. The
correct command is "route add -net 127.0.0.0".
Workaround: Change in /etc/sysconfig/network-scripts/ifcup-lo
the "route add -net ${IPADDR}" into "route add -net 127.0.0.0"
Workaround: Change in "/etc/sysconfig/network-scripts/ifup-lo" the
