Comment 9 for bug 1717995

I still have this problem. When I disconnect from a VPN, the various resolv files retain a search line and DNS lookup fails for the domain associated with the VPN (in this case, my university). Luckily, this is fairly easy to work around (I no longer reboot to try to fix my network). Did I miss something? Or has the fix been committed, but not yet propagated out into a new systemd package in the repos? The post above seems to indicate that the version 234-2ubuntu12 and above would have the fix. I have 234-2ubuntu12.2 which I presume is newer.

here's output from dpkg-query -s systemd:

Description: system and service manager
 systemd is a system and service manager for Linux. It provides aggressive
 parallelization capabilities, uses socket and D-Bus activation for starting
 services, offers on-demand starting of daemons, keeps track of processes using
 Linux control groups, maintains mount and automount points and implements an
 elaborate transactional dependency-based service control logic.
 .
 systemd is compatible with SysV and LSB init scripts and can work as a
 drop-in replacement for sysvinit.
 .
 Installing the systemd package will not switch your init system unless you
 boot with init=/bin/systemd or install systemd-sysv in addition.
