Scrapping a kernel

MadCactus · 07-10-2003, 05:40 PM

So while trying to understand the kernel building process I have created an abomination that must be totally erased. Is there a command like "make remove-kernel"?

I suppose its easy enough to delete the kernel image itself , system.map and initrd - but what about any other config files, and all the modules?

Does a kernel build scatter files all over the place? Is anything shared with previous kernel versions?

All the modules and configs are stored in /usr/src/linux-x.x.x
Once you remove that directory and the vmlinuz and initrd files, you have effectivly deleted the kernel. Be careful.

If you didn't change the version-number
(Extraversion) in the makefile the newly
compiled kernel uses the same module-
directory ...
/lib/modules/<version>.<patchlevel>.<sublevel>.<extraversion>
Other than that, the installation should
only include the bzImage and the System.map.

Doh! I totally forgot the modules aren't stored in the kernel directory. Good catch Tink..

Thanks!

The reason I was asking is there isn't (afaics) a modules directory for each kernel in /usr/X11R6/lib, just the one /modules dir.

But I am thinking this will not matter - the X modules + drivers will be the same for any kernel, just as long as you have the right module loaded for your video card, right?

Heh ... not really a catch ;) We more or less
posted at the same time, 36 seconds apart :}

Well, let's say that in terms of AGP
and DRI there is interaction between
Kernel & X, and some cards use DRI
quite excessively...

Mine being a PCI nVidia card does not use DRI according to the status list, so (hopefully) that means I don't have to touch any X modules, right?
