[oe] Missing kernel modules in OE 2011.03

[Hauser, Wolfgang (external)]

Hi,

the package kernel-modules-xxxx.ipk is a meta package containing runtime
dependencies to all modules compiled with the kernel, created while
bitbaking a kernel (kernel.bbclass).
It should trigger an install of all configured modules to the image.

>Is there ever a case when you do not want to have the modules

It may be someone wants to have a "general" modulized kernel, but
depending on the machine/distro capabilities/needs only some of the
modules should be available, then you are able to install the needed
kernel-module-xxx.ipk packages only. This mainly saves space and limits
the available functionality to the needs.

If the system is running well, it may be better to compile all modules
into the kernel.

If the image includes task-boot, the modules to be installed are
configured in <machine>.conf.
