This has irked me for a while. For me network configuration is the stuff
we store on disk in configuration file. And networkd then *applies* the
configuration. But the units so far claimed that networkd was the
"configuration" itself. Which I guess might make sense to some, but to
me sounds a bit unprecise. Let's clean this up, and call what networkd
is doing "Network Management".
These are all services that valid to be run in the initrd, so let's
make sure they have the appropriate dependencies on
initrd-switch-root.target so that they are stopped when we're about
to switch root.
