By default, the application in the system crashes, making the core call Systemd-coredump to generate the associated memory image and some debugging information. If the application is running with a large memory footprint, these debugging information will quickly fill the hard disk space. Application crashes are a common thing, but the average user doesn't have to debug it, and most people don't know how to debug it. So it's a good choice to disable it

First, init stops all services and the file system will be uninstalled at the final stage. The above mentioned startup process has some shortcomings. It has been a long time to replace the traditional init with a better me
