 I use the following unit in one of my servers:
 
 #

 [Unit]


My current version, using ip :

# cat network.service
[Unit]
Description=Network Connectivity

[Service]
Type=oneshot
RemainAfterExit=yes

EnvironmentFile=/etc/conf.d/network_systemd
ExecStart=/bin/ip link set dev ${interface} up
ExecStart=/bin/ip addr add ${address}/${netmask} broadcast ${broadcast}
dev ${interface}
ExecStart=/bin/ip route add default via ${gateway}

ExecStop=/bin/ip addr flush dev ${interface}
ExecStop=/bin/ip link set dev ${interface} down

[Install]
WantedBy=network.target

- so that unitfile does not have to be touched again and you only
edit /etc/conf.d/network_systemd -

# cat /etc/conf.d/network_systemd
PATH=/sbin:/usr/sbin
interface=p4p1
address=192.x.y.z
netmask=255.255.255.0
broadcast=192.x.y.zz
gateway=192.x.y.zzz

-

I have a second unitfile with a more complicated setup for bridging
(with KVM).

Good idea, I already had forgotten that you could parse variables from 
another file in a systemd unit.

Why not continue to use DHCP and simply set a static assignment based on
the MAC inside the DHCP server? Then it doesn't matter how the system is
setup, it just works...

There's no DHCP in this particular offsite data center :-)

 Howdy folks,

 currently I am migrating some servers to systemd, and I am wondering
 what's the best way to set up static networking. Until now, I always
 used dhcp + networkmanager (workstations, laptops).

 Some suggested creating your own network unit and manually start
 ifconfig/route or ip via ExecStart, some suggested Arch's netctl which
 seems to support static addresses and brings a systemd unit file.

 At the moment, following the KISS principle, I tend to a customized unit
 file.

 What do you use - and what are the benefits of your method?

I use the following unit in one of my servers:

# 
---
[Unit]
Description=Static network service
After=local-fs.target
Documentation=man:ifconfig(8)
Documentation=man:route(8)

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/bin/ifconfig DEVICE IP broadcast BCAST netmask NETMASK up
ExecStart=/bin/route add default gw GW DEVICE
# 
---

Obviously, change the necessary parameters.

The benefit is that it doesn't get any more simple, I believe. If DHCP
is available and I don't want to use NetworkManager, I use the
following unit:

# 
---
[Unit]
Description=DHCP on %I
After=basic.target

[Service]
ExecStartPre=/bin/ifconfig %I up
ExecStart=/sbin/dhcpcd -B %I

[Install]
WantedBy=multi-user.target
# 
---

You can then enable the unit with:

systemctl enable dhcpcd@DEV.service

where DEV is enp0s0, or whatever funny name udev gives to your network
card. I think I got the unit from Arch, or maybe I wrote; I honestly
don't remember.

Regards.

Tanks. I will give netctl a try in a VM. For now, on real machines, I am
going with the unit you suggested.

I'm using netctl on one VM now. I'm... ok with it. for now... it did
seem to break during one update, so I think it's still in flux. And the
configuration is a bit confusing.
