altboot: - Allow a basic reconfiguration of non-flash based installations:

		- Move /home from flash into the image
		- Remove SD / CF / /home ipkg dests
		- Move ipkg package data from RAM into the image
		- All of the above is _optional_
	- Be a little bit less verbose.
	- Yet _again_ change the way we detect wheter we are called by the kernel or the user...this is driving me nuts.
