yep, i guess size_of_installer will depends what stage the installer is
at as to how much memmory it will need, but i guess we can estimate that
ok.

Maybe we need to be more descriptive with the retriever modules, we
(may) need to describe

1) Which installer was one the boot medium, this should be in a working
state from the start.

2) The preference in which to installers should be tried, e.g. try the
CD retriever first, then try the net retriever is the cd retriever
doesnt return whats needed.

The retriever in 1) will also have a preference value associated from 2)
whioch might change, but 1) will always be the same.

For pp we could split the net retriever to ppp net retriever and eth net
retriever, butthat oculd get confusing.... Maybe we need a more general
solution as it may be other modules as well.
