Maybe but in this case the size of the initial download we present
on the web page is the important one. 350 just looks odd for
something we call small :-) Even the 100MB are quire large already.

Well, linuxrc does a kexec if needed. That seems to work quite well
and is transparent to the user.

That unfortunately is an illusion that may or may not work. The
instsys will use the built in control.xml and may not understand a
newer control.xml anyways. So if there are any changes in the way
things are configured, like retiring DEFAULT_WM in favor of
update-alternatives, the old installer would in the best case
configure things in useless ways. The only safe thing is matching
kernel, initrd, instsys AND repo.
