Yes.

What will happen if I try to install a system that has an existing
corrupt vfat filesystem on a removable USB storage device? Or install a
system that has a big USB storage device with a very large number of
small files? (Appears this code will put the whole filelist in memory?)

There appears to be no system to recognize what drivers are actually
appropriate for this installation. E.g. it will not work well if there
are different drivers needed for different distributions. or for 32bit
vs 64bit.
