[Bug 1492546] Re: ifdown stops LTSP's "manual" interface on shutdown

[Alkis Georgopoulos]

I'm closing the LTSP task as LTSP 5.5.6 got released and was published
in Xenial without the fix being included, and the newer ifupdown makes
the fix not necessary anymore.

** Changed in: ltsp (Ubuntu)
       Status: Triaged => Won't Fix

Title:
  ifdown stops LTSP's "manual" interface on shutdown

Status in ifupdown package in Ubuntu:
  Fix Released
Status in ltsp package in Ubuntu:
  Won't Fix
Status in ifupdown package in Debian:
  Fix Released
Status in ltsp package in Debian:
  New

Bug description:
  The unit /lib/systemd/system/ifup at .service is Debian and Ubuntu specific, it's not part of upstream systemd.
  On shutdown, it unconditionally ifdowns all interfaces:
    ExecStop=/sbin/ifdown %I

  This is a regression from previous init systems (sysvinit and upstart)
  which cared so that when a network file system was in use, they didn't
  ifdown the interfaces.

  Specifically, both /etc/init.d/networking and /etc/init/networking contain these functions:
    check_network_file_systems()
    check_network_swaps()
  which output the message "not deconfiguring network interfaces: network file systems still mounted" and exit.

  So, please call the same functions in the ExecStop= part of
  ifup at .service.
