... is just useless. resolv.conf is already owned by root, DCHP client 
daemons run as root and on Linux systems root (uid 0) ignores read/write 
permissions.

No, it solves nothing. Without resolvonf the DHCP client will write 
directly in resolv.conf.

This does not work.
The resolver stops as soon as it receives a positive (record exists) or 
negative (record does not exist) answer. If it receives a negative 
answer from the first name server, it won't query the next name server.

All name servers declared in resolv.conf must be equal and provide the 
same answers, or unexpected behaviour will happen. Multiple name servers 
is only for redundancy and load balancing, not to provide different answers.
