I'm beginning to think that resistance is futile and have started to accept
the inevitability of NM.  OTOH, I run my own name server for my tiny home
network and was none too pleased to find NM wiping my name server out of
/etc/resolv.conf.

I was querying this list about a somewhat-related problem when somebody (don't
recall the name offhand) made the brilliant suggestion to mark resolv.conf as
"immutable".  I've added the following to my resolv.conf to remind me of what
I did and how to undo it:

    #
    # I've marked this file as "immutable" via:
    #
    #    chattr +i resolv.conf
    #
    # To undo that:
    #
    #    chattr -i resolv.conf
    
I haven't been mugged by NM since I did this.

BTW, I did the same thing to my iptables file to keep some helpful system
utility (NM?) from messing with my configuration.
