[SOLVED] - GRUB2 kernel boot parameters

[warron.french]

Where can I get a complete list of all of the parameters given on the linux16 directive line for a menuentry in /boot/grub2/grub.cfg?

For example, from this syntax:

Code: Select all

linux16 /vmlinuz-3.17.4-301.fc21.x86_64 root=/dev/mapper/fedora-root ro rd.lvm.lv=fedora/swap rd.lvm.lv=fedora/root rhgb quiet LANG=en_US.UTF-8

Where would I find an explanation of ro, rd.lvm.lv, rhgb or quiet?

I have read over 15 different websites and none of them give me a consolidated list (deprecated or current) and their purposes. This is what I am trying to resolve.

P.S. The are called kernel boot parameters right?

man dracut.cmdline will tell you most. You can also read /usr/share/doc/kernel-doc-3.10.0/Documentation/kernel-parameters.txt for kernel specific things but it would appear that file is no longer shipped with el8 or Fedora 32.

Awesome, thanks @TrevorH.
