fails after NetworkManager

With additional changes,

# /etc/systemd/system/sshd.service.d/01-after-network.conf
[Unit]
After=NetworkManager-wait-online.service

[Service]
Restart=always
RestartSec=5s
RestartPreventExitStatus=

SSHD comes up *most of the time* while still failing sometimes. That is,
Network Maanger signals via NetworkManager-wait-online.service that it is
complete, but the IP address is still not available for bind by SSHD. I've
attached a log that shows exactly this.
