Re: [uml-user] another networking error

[Martin P. <ma...@cs...>]

The compilation chapter in UML book instructs that the user
do only:

% make ARCH=um

How is this going to install the modules? Am I right that I need to do
more work to
install the modules and how do I do it? Could this be the problem
causing networking
setup to fail? In any case, when I was halting the UML instance I was
getting a lot of
errors like this:

modprobe: FATAL: Could not load /lib/modules/2.6.23.12/modules.dep: No
such file or directory
