Components provide this information in their own language and I have to generate systemd configuration for them. It's more complex than just rebooting the node so I couldn't use FailureAction.

Right but you already have
Restart=on-failure
RestartSec=...

and the likes to restart the services in graceful HA manner ( and at the 
sametime allowing it to fail gracefully ) so what I was curious about 
what else you are doing in the background since it might lead to a worse 
situation in HA setup by doing so depending on the HA setup ( split 
brains etc you know the drill ).
