How to permanently disable EEE (Energy Efficient Ethernet) on network card
On system bootup, if dmesg shows following warning,
kernel: igb 0000:01:00.3: exceed max 2 second
We can disable Energy-Efficient Ethernet (EEE)[1] of NIC. To disable EEE on network card we can use systemd service unit to run the ethtool command (e.g. /etc/systemd/system/disable-eee.service[2] )
/etc/systemd/system/disable-eee.service
Description=HM disable eee on NIC
Before=network-pre.target

How to read live-tail logs of multiple services with journalctl
#Systemd - How to read live-tail logs of multiple services with journalctl[3] $sudo journalctl --follow _SYSTEMD_UNIT=docker.service + _SYSTEMD_UNIT=apache2.service
Ensure the mount path is accessible before the service
<[Unit] RequiresMountsFor=<path required>
This will ensure the path is accessible before starting the service and also will mount it if it's not already (unless it has noauto specified).
