No, usually, the modules.dep file gets built when you boot your
linux box.  As part of the rc.sysinit script.

But, with LTSP, it doesn't do that as part of the boot, it does
that when you build the initrd, with the buildk script.

The modules.dep file is needed by the 'modprobe' command, so it
can figure out what modules are dependencies of other modules.

Try mounting the initrd image, and poke around there and see if
you can find the modules.   You should be able to figure out where
the file is, based on the buildk script.

That would be great.
