> NM kills and starts a new dnsmasq process every time this file changes. Will that be a problem for your LTSP setup where dnsmasq is also the DHCP server?
The most time consuming operation that dnsmasq does in our setups is sending the kernel/initrd via TFTP. That takes a few seconds. If the teacher activated a VPN connection at that time and dnsmasq was killed+respawned, the client wouldn't boot. But I think that problem would be too rare, so it sounds acceptable. I don't quite understand why dnsmasq needs to be restarted though. /var/run/nm-dns-dnsmasq.conf only contains the nameservers, and dnsmasq supports polling a resolv.conf for changes. Can't that be used instead to completely avoid restarting dnsmasq? (it wouldn't even need a SIGHUP in that case...) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/959037 Title: NM-controlled dnsmasq prevents other DNS servers from starting Status in “djbdns” package in Ubuntu: New Status in “dnsmasq” package in Ubuntu: Confirmed Status in “network-manager” package in Ubuntu: Triaged Bug description: As described in https://blueprints.launchpad.net/ubuntu/+spec/foundations-p-dns- resolving, network manager now starts a dnsmasq instance for local DNS resolving. That breaks the default bind9 and dnsmasq installations, for people that actually want to install a DNS server. Having to manually comment out "#dns=dnsmasq" in /etc/NetworkManager/NetworkManager.conf doesn't sound good, and if it stays that way, it should be moved to the bind9 and dnsmasq postinst scripts. Please make network-manager smarter so that it checks if bind9 or dnsmasq are installed, so that it doesn't start the local resolver in that case.
