  • aboot-0.9b 

    Submitted By: Joe Ciccone <jciccone@linuxfromscratch.org>
Date: 2006-06-25
Initial Package Version: 0.9b
Upstream Status: NONE
Origin: Joe Ciccone
Description: This patch fixes compilation issues with aboot-0.9b.
        This patch creates kernel headers that the makefile would
        normaly take out of the kernel source or that are not
        included with the linux-headers package installed in the
        system.
