+Subject: [PATCH] debian: fixup networking.service
+
+Add missing ordering:
+  After=network-pre.target
+    See systemd.special(7)'s description of this target
+  After=systemd-sysctl.service
+    ifupdown does the same - we want net.*.conf.default.*
+    sysctl keys to apply to newly created interfaces
+  After=systemd-modules-load.service
+    ifupdown does the same, though this should be mostly
+    optional as modules should be autoloaded anyway
+  Before=network.target
+    This is required to prevent services which require
+    network to be started too early and listen on wrong
+    addresses (iow. only on loopback or ipv4-only).
+  Before=network-online.target
+    See systemd.special(7)'s description. We are the
+    provider of this target.
+  Before=shutdown.target
+    ifupdown does it this way, it also makes more sense
+    given the Conflict entry, compared to the previous
+    WantedBy entry in [Install]
+
+Changed install section:
+  WantedBy=multi-user.target
+    I wasn't sure about this. ifupdown does this.
+    basic.target didn't seem useful since we actually want:
+  WantedBy=network-online.target
+    We provide this, so we should be installed into it.
+  removed WantedBy=network.target
+    We strictly want to be ordered before this and instead
+    are required by multi-user.target already.
+  removed WantedBy=shutdown.target
+    I didn't see the point.
