	  If you need patches applied to your vanilla kernel
	  you can specify a series file here. A series file
	  is a textfile with one patch per line.
	  This file lies usually in your project directory,
	  so the default is $(PROJECTDIR)/series.
	  The patches given in the series file must be relative
	  to the series file

	  Usually config files for the kernel live in $(PROJECTDIR), so

	  Say yes if you intend to use an external already configured 
	  kernel tree. You want this if you, for example, are currently

	  for each and every PTXdist run. 

config KERNEL_DIR

	  Add a path to your external kernel here. The kernel must be
	  configured.

	  This switch adds "ssl0=fd:0,fd:1" to the kernel command line,

	  host's stdin/stdout. 

config KERNEL_HOST_CMDLINE

	  Add your custom kernel commandline for the user mode linux
