After having updated to the world past 2002-02-19, dhclient started
very fast cycle of acquiring and releasing leases every time it was
attached to the local network, like it's attacking the DHCP server.
After all, it was /sbin/dhclient-script that failed trying to update
/etc/resolv.conf which had schg turned on (I needed this to prevent
ppp from replacing resolv.conf when my / was mounted read-write,
until I found 'resolv readonly' option in in ppp(1) manual).
The fix below also covers read-only root filesystem case.
