That may be a reason to develop the not-specific (sorry...) idea that installworld
should install to a small duplicate of  where it Does, and  complete, before the Actual
installworld so that if the latter cannot complete, a small rescue shell with rsync
embedded or an equivalent can copy the bare-minimum set of files over the 
mixture of new and old... which I have had to several times do more or less
piecemeal, and more often than not sufficed to bring the system back whole.
