Strictly speaking, Network Manager doesn't change /etc/resolv.conf unless
it is configured with static DNS information, or uses DHCP to fetch the
same. A reboot alone does not cause this to happen.

Note also that if you were previously using DHCP on an interface, then
later configure it statically in /etc/network/interfaces, that the
dhcp-client instance may still be running. It will periodically refresh the
address. Kill it manually or reboot.
