Out of interest, is there an accepted way of having multiple kernels of
the same version on a system with non-shared module directories?

By default modules reside under /lib/modules/xxx where xxx is the kernel
version - there's no obvious way I've seen of tying it to a particular
installed kernel of that version... (say by suffixing the module directory
with a user-supplied tag that's also embedded in the kernel at build time)

I assume the problem will have been addressed in 2.6.x kernels... :-)

cheers

Change the path where each kernel looks for his modules, but what's the
point in doing so?

Why don't you want to give your different kernels different version
numbers?

Edit the Makefile in the Kernel source directory and change the
EXTRAVERSION for each kernel you build.

Sure - give them different EXTRAVERSION names and (thus) different
module directories.

You can't rely on modules compiled differently to work with each other
and differently cmpiled kernels (of the same version). But they might.

If you wnat to take that chance, set EXTRAVERSION the same for all of
them, and they will share.
