Ever wondered how to automatically lock your screen when you put your laptop to sleep? Like me you most likely found a SystemD unit file looking a lot like the one below. What annoyed me though was that the lock command would be executed after the system reached the sleep target, ergo when waking up. This resulted in a brief flicker where my screen was visible before i3lock kicked in.
Quick note to myself.
Having an environment where some services (LDAP, Radius, ...) that the F5 needs to access are not reachable from the Virtual Server but only via the management interface can be tricky. Adding a specific route to the host in question will solve this.
