параметры командной строки ядра (Kernel command line parameters)
Описание (Description)
The kernel, the initial RAM disk (initrd) and basic userspace
functionality may be configured at boot via kernel command line
arguments. In addition, various systemd tools look at the EFI
variable "SystemdOptions" (if available). Both sources are
combined, but the kernel command line has higher priority. Please
note that the EFI variable is only used by systemd tools, and is
ignored by the kernel and other user space tools, so it is not a
replacement for the kernel command line.
For command line parameters understood by the kernel, please see
kernel-parameters.html
[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.
