The Linux kernel accepts boot time parameters as it starts to boot system. The bootloader load Linux kernel to RAM and then it boots kernel with these parameters. These parameters are used to inform kernel about various hardware or kernel behavior.

You need boot time parameters for:

  • Troubleshoot system
  • Hardware parameters that the kernel would not able to determine on its own
  • Force kernel to override the default hardware parameters in order to increase performance
  • Password and other recovery operations

The kernel command line syntax

name=value1,value2,value3
