Introduction to systemd’s Restart Behavior
If you’ve worked with Linux for any length of time, you’re probably familiar with systemd, the system and service manager that’s become a core component of most modern distributions.

However, there are situations where the default restart behavior may not be desirable - and that’s where RestartSec comes in.
