Which command is used to investigate your system's boot performance and check for potential system initialization problems?

The command that is used to investigate your system's boot performance and check for potential system initialization problems is systemd-analyze. This tool is part of the systemd suite and provides useful metrics about the boot process, including the amount of time taken by the kernel, initrd, and user services to start. It can also help identify which services are taking the longest to initialize, allowing system administrators to pinpoint potential issues that may be slowing down the boot process.

Systemd-analyze has several commands that can provide detailed insights, such as systemd-analyze blame, which lists all services sorted by the time taken to start, and systemd-analyze critical-chain, which shows the critical path of services that were needed for booting.Using these insights, administrators can optimize the boot process by adjusting service configurations, enabling or disabling services as necessary.

Other commands may also relate to system management or service handling, but they do not provide the specific boot performance metrics and diagnostics that systemd-analyze focuses on, making it the most appropriate choice for this purpose.
