Re: Starting a service before any networking

[Jetchko Jekov <jetchko.jekov@xxxxxxxxx>]

A good example of a service that needs to be started before networking
is the firewall service.
You can take a look at what your distro of choice is providing for hints.
But essentially it boils down to something like this:

Fedora's iptables.service:
Before=network-pre.target
Wants=network-pre.target

Ubuntu's ufw.service (bit more elaborate, no idea why):
DefaultDependencies=no
Before=network-pre.target
Wants=network-pre.target local-fs.target
After=local-fs.target
