** Description changed: The resolvconf package comes with /etc/dhcp/dhclient-enter- - hooks.d/resolvconf which, if /sbin/resolvconf is present, undefines - make_resolv_conf() (previously defined by dhclient-script) and calls - resolvconf. + hooks.d/resolvconf which, if /sbin/resolvconf is present, redefines the + make_resolv_conf function (previously defined by dhclient-script) to + send nameserver information to resolvconf instead of writing it directly + to /etc/resolv.conf. - However, the hook checks if /etc/resolv.conf is a symlink even though - /sbin/resolvconf already handles this. + However, the hook also checks if /etc/resolv.conf is a symlink. This is + problematic because if /etc/resolv.conf is not a symlink then the script + does not redefine make_resolv_conf() and so dhclient will overwrite + /etc/resolv.conf when it configures an interface, even though the + resolvconf package is installed. - This is problematic because it never undefines the make_resolv_conf - function which dhclient-script defines itself. + The behavior I would expect would be /etc/resolv.conf never changing if + resolvconf is installed and /etc/resolv.conf is not a symlink. - For me, the expected behavior would be /etc/resolv.conf never changing - if resolvconf is installed and /etc/resolv.conf is not a symlink. + Debian implements the behavior I would expect. - At the very least, I think this behavior should be documented in the man - pages for resolvconf. Furthermore, debian does not implement this patch - and it exists starting in 12.04 until current. + At the very least, I think that the different behavior in Ubuntu should + be documented in the man pages for resolvconf. - As far as I can tell, there's absolutely no reason to check it twice if - resolvconf already implements it. + As far as I can tell, there's no reason to check for /etc/resolv.conf + being a symlink when resolvconf itself already does that. - It was introduced by: http://bazaar.launchpad.net/~ubuntu- + The patch was introduced by: http://bazaar.launchpad.net/~ubuntu- branches/ubuntu/trusty/resolvconf/trusty/revision/32/etc/dhcp/dhclient- enter-hooks.d/resolvconf
