From: Christopher Spinrath christopher.spinrath@rwth-aachen.de
Currently, entire script segments have to be changed in the default environment to change the kernel image location or to append kernel cmdline parameters. In the later case this has to be changed for every possible boot device.
Introduce new variables for kernel image locations and boot device independent kernel parameters to make it easier to change these settings.
