This sounds very similar to https://launchpad.net/bugs/1492546 . ifupdown's /etc/init.d/networking (and also /etc/init/networking.conf) call functions check_network_file_systems() and check_network_swap() and don't tear down the interface(s) in the above situation. This also applies to e. g. iscsi. But we don't do the same with the autogenerated ifup@.service -- that always unconditionally calls "ifdown" on stopping. IMHO we should make "systemctl stop ifup@ethX.service" a no-op at least during shutdown, as stopping /etc/init.d/networking will stop them all anyway (or not, if network file systems are being used). We could change the ExecStop= to something like /bin/sh -ec '[ "$(systemctl is-system-running)" = stopping ] || /sbin/ifdown %I" Or we just declare that we don't support manual stops, and you are supposed to run "sudo ifdown ethX" to stop an interface. This is also reasonable as we consider ifup@.service more like an internal helper unit, not an user-visible/actionable one. For sure I don't want to replicate the entire check_network_file_systems()/check_network_swap() logic in ifup@.service -- running this once on shutdown is bad enough :-) Thanks, Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)
