Checking for network online

Probably not, it's required to implement network-online,target, which
is standard, and may be referred to by arbitrary packages.

There's some good background on the issues you're experiencing here:

 https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/

in short: most services should be able to start before network-
online.target, and be able to adapt to changes in network configuration
after that point.

For your specific issue there:

> Issues: This service blocks entry to multi-user.target.
> phosphor-state-manager uses multi-user.target to report the BMC is
> ready to use.
> This is reported via IPMI Get Device ID.

That sounds like more of an issue of whether that reported state
actually represents the expected BMC state...

Regards,
