This patch changes libkmod so it honors the 'LINUX_MODULE_DIRECTORY'
|
|
environment variable, rather than looking for modules exclusively in
|
|
/lib/modules.
|
|
|
|
Patch by Shea Levy and Eelco Dolstra, from Nixpkgs; adjusted to
|
|
use 'LINUX_MODULE_DIRECTORY' rather than 'MODULE_DIR' as the variable
|
|
name.
