On my system (Wheezy recently upgraded to Jessie):

| ● networking.service - LSB: Raise network interfaces.
|    Loaded: loaded (/etc/init.d/networking)
|   Drop-In: /run/systemd/generator/networking.service.d
|            └─50-insserv.conf-$network.conf
|         /lib/systemd/system/networking.service.d
|            └─network-pre.conf
|    Active: active (exited) since Sun 2016-03-20 21:56:51 CET; 1 weeks 3 days ago

/run/systemd/generator/networking.service.d/50-insserv.conf-$network.conf
contains only:

| # Automatically generated by systemd-insserv-generator
| 
| [Unit]
| Wants=network.target
| Before=network.target

/lib/systemd/system/networking.service.d/network-pre.conf contains only:

| [Unit]
| After=network-pre.target

No trace of systemd-sysctl.service anywhere.

This works for per-interface options, but not for /net/ipv6/conf/default.
(However, I probably should abandon using conf/default anyway, since some
kernel modules are loaded before sysctl is set.)
