List of Kernel Parameters
All Linux distros keep a copy of a list of the configurations that were used when the distro was built. You might want to have this information for future use. An example would be if you were to install an application that modifies one or two of these the parameters and ends up not working as expected. You can refer to these configurations to restore previous settings.
In some Linux distros (especially those built native), you can find a copy of these configurations is a file name .config located in /usr/src/linux. Now, if you installed from a binary distribution (which is most likely the case), then the .config file will not be found there.
In my Ubuntu distro, like most others, the file is found here:
where the last part corresponds to the kernel version of your installation. You can see the contents in my case by entering:
You can find a full parameter list by going to this location on your installation if you have included the source. Otherwise in the references at the bottom, you can find a full link to an online resource with the same information spanning about 2700 lines of code.
Where <kernel-version> should be the appropriate version.
