I wouldn't count on it. In recent encounters with NetworkMangler on a 
fedora VM I found that it overwrites files it considers iteslf to own 
even when I tried to turn it off or set the files to be read only.

It's a horrid hack, but if you can't remove it, I found that making 
files you don't want it to touch immutable does the trick - e.g.

sudo chattr +i /etc/resolv.conf
