Hey Danny,

Reading 'depmod' manpage, I understand that -E and -F are mutually
exclusive. Both options seem to have an interest only if -e is supplied
to "reports any symbols which a module needs which are not supplied by
other modules or the kernel".

So maybe something like "-F (string-append #$linux "/System.map") -e"
would make more sense ?

Mathieu
