/lib/modules/kabi-4.0-0*

[Björn Augustsson <august chalmers se>]

Hello folks!

Recompiling third party modules after every kernel upgrade is a
constant PITA. 

Now, there's a directory called kabi-4.0-0 in /lib/modules/. 
I remeber vaguely from somewhere that RH maintains a compatble 
kernel ABI within a release, and I guess this has something to
do with it.

But it's not clear to me how it works. Is there any special tricks
to make modules use this? Can I just take a standard module, built 
against, say, 2.6.5-11, and move the .ko into the kabi dir and have
it DTRT? Or what?

I haven't found any docs on this, and as far as I can deduce from a
running system, neither module-init-tools not mkinitrd knows anything
about the kabi directories.

Anyone?

/August, yes, I know about DKMS and how it uses some brand of magic to
         basically do this. But I'm worried about the more, ahem, naive
         modules we have to use.
