also i think this can be inaccurate if err != nil - I looked at SdNotify and it'll return false with a non-nil error so this log might be confusing?

The logging was partially to assist implementation, but could also help people debugging since it requires correct configuration in systemd to work as well. You're right that the if sent/else block should only happen if err is nil.

This is a noop on systems without systemd, and when not spawned by systemd. Note that "Type=notify" must be specified in the systemd service definition in order for systemd to spawn a notification socket and set the corresponding environment variable.
