Prevent netctl from modifying resolv.conf
I want to manage my resolv.conf, but when I load a profile and I comment out the 'DNS...' line, resolv.conf becomes blank. How do I tell netctl not to touch to resolv.conf?
My solution so far is to modify this line in the resolvconf.conf file :
resolv_conf=resolv.conf2This way, when netctl uses resolvconf to modify resolv.conf, it modifies another file.
But there must be a better solution?

Re: Prevent netctl from modifying resolv.conf
I forgot to mention that I have a static IP. Your link seems to talk about dhcpcd. I don't think it would apply to my problem. I might be wrong though...

Re: Prevent netctl from modifying resolv.conf
Did you try commenting the "resolv_conf" line? If commenting the line works, then you can accept the solution as intended behavior. Try and see if the service throws an error (via systemctl status for example).

Re: Prevent netctl from modifying resolv.conf
It seems like your solution works. Strangely, the timestamp of resolv.conf is updated, but the content is not modified...

A little late suggestion, but you could make the file immutable with chattr.

Re: Prevent netctl from modifying resolv.conf
That's odd. I thought chattr was already mentioned in this thread, because after reading it, I disappeared in man chattr for a while. Weird.

Re: Prevent netctl from modifying resolv.conf
In my opinion, it is a good idea to have profile specific nameservers. If you want fallback nameservers, add them using name_servers_append in resolvconf.conf. If you want a nameserver which is always queried first, use name_servers.
Edit: If you really want a static resolv.conf, then uninstall openresolv and replace it with a dummy package which links resolvconf to /bin/true.

Re: Prevent netctl from modifying resolv.conf
I'm so glad I've never migrated from netcfg.
Overwriting resolv.conf is the sort of horribleness reserved for the likes of gnomes' networkmanager.
DON'T TOUCH MY CONFIGURATION FILES FFS.
Thank you and good night.
You're just jealous because the voices only talk to me.

Re: Prevent netctl from modifying resolv.conf
Well, moetunes, resolv.conf has always been subject to automated changes on dynamic network configurations.
