That works in fedora, but even better (as others have said)
is disabling NetworkManager service and enabling network instead
(i.e. go back to the old and unimproved days :-).

I have had to use the chattr thing as the best I could find
on various different flavors of linux distributions. I've been
doing battle with a host of virtual machines we use for testing
software on different distros, and to get networking up and NFS
filesystems mounted on all of them at boot time has been like
herding cats - every one of them has some different quirk
to work around. The most interesting was openSUSE - if you
try the chattr trick there, the whole boot comes to a screeching
halt and it prints a console message saying "Oh No! I can't
screw up your /etc/resolv.conf file, what should I do?"

Fortunately the /etc/resolv.conf file itself on SUSE contains
generated comments telling you exactly how to fix it the "official"
way. So SUSE are idiots for checking for an error they can't
handle, but they are geniuses for actually putting the information
you are gonna want to know right in the resolv.conf file instead
of just leaving you hopelessly lost.
