NAME

       kernel-command-line - Kernel command line parameters

SYNOPSIS

       /proc/cmdline

DESCRIPTION

       The kernel, the initial RAM disk (initrd) and basic userspace functionality may be
       configured at boot via kernel command line arguments.

       For command line parameters understood by the kernel please see kernel-parameters.txt[1]
       and bootparam(7).

       For command line parameters understood by the initial RAM disk, please see
       dracut.cmdline(7), or the documentation of the specific initrd implementation of your
       installation.
