"clean" removes files, while "drop" only remove state information.

PTXdist works with states for every single package. It walks through the ma=

states in the following order:

 - get: get package sources
 - extract: extract package (its archive for example)
 - prepare: run configure stages for this package
 - compile: compile the sources of this package
 - install: install the results into the corresponding sysroot/
 - targetinstall: create the content for the ipkg and install files for tar=
get
                  into root/

So it depends on what you want PTXdist to do again. If you have modified =

      ptxdist targetinstall kernel
