Aa couple of times I've felt the urge to do that. Something was breaking
/etc/resolve.conf and I couldn't discover what. chattr fixed that one.
I used the same solution, but I knew what it was: the DHCP client. It
overwrites /etc/resolv.conf with the information from the DHCP server. And
since it runs as root, it can overwrite a "read-only" file. The immutable
bit stopped that.
Later I discovered that the DHCP client script will accept a setting in the
interface config to ignore DNS information from the server.
