Re: modutils 2.4.2, please test asap

[David Brownell <david-b@pacbell.net>]

Ah, but the hotplug utilities use it.

A pure 2.2 system (kernel + modutils) has no "modules.*map" files.
A pure 2.4 system (ditto) does have them.

But 2.2.18 kernel + 2.4 modutils will generate "modules.*map" files,
which is not compatible with the previous behavior of 2.2 modutils
with such kernels.

I forget (haven't used 2.2 in a long time) -- does 2.4 modutils
keep to the 2.2 style module tree on 2.2 kernels, or does it change
that around too?
