What I don't understand is that, then if I manually remove the 'dns=none' setting and either restart NM and/or reload+reactivate the profile, /etc/resolv.conf is not, as I was expecting, emptied by NM.
Hi, I am not sure from the description. To be sure level=TRACE logging and check the logfile. But I think the reason is that NetworkManager doesn't want to write an empty /etc/resolv.conf file. If Networkmanager has no nameservers, it doesn't seem very useful to enforce that /etc/resolv.conf is empty. Either, /etc/resolv.conf is already empty, then there is no effect. Or, /etc/resolv.conf happens to contain correct name servers, then clearing the file only breaks something that otherwise would work. Or, /etc/resolv.conf contains invalid nameservers. But writing no nameservers also isn't going to make it work. best, Thomas
