You’ve had a lot of advice, but I’m not sure anyone’s made clear that:

quiet isn’t really a grub option. It’s passed straight through to the
kernel.

You can find documentation on these kernel parameters in
/usr/share/doc/kernel-doc-2.6.30.8/Documentation/kernel-parameters.txt
which is in the kernel-doc package.

Some of them are pretty low-level.

If the kernel doesn’t understand what to do with a parameter, it ignores
it, but it (still) makes it available to the start-up scripts, which may do something with it. A good example of this is rhgb.

Hope this helps,

James.
