All above and way beyond me, but from a cursory online examination of this affair it appears that beyond disabling rdnssd entirely, it's necessary to modify or patch the /etc/rdnssd/merge-hook script to prevent rdnssd from overwriting /etc/resolv.conf. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=767071 /etc/resolv.conf is handled by a configurable /etc/rdnssd/merge-hook script that users can modify to suit their needs. The stock version upstream has been modified to do what you want for ages: http://git.remlab.net/gitweb/?p=ndisc6.git;a=blob_plain;f=rdnssd/merge-hook.in;hb=f7bd3662d2292e248173721d4760c03df39df666 Good luck. -- "J'ai pour me guérir du jugement des autres toute la distance qui me sépare de moi."
