The problem with this is that coming up with the split values when you
only have 8 GB or 10 GB or 15 GB is way harder, and the consequences of
getting it even a little wrong are much larger.  If the user's got 200
GB to work with and we end up making / 5 GB too large, probably not a
problem.  If they've only got 10 GB to work with and we make / 2 GB too
large, that's probably a much bigger problem.

Well, see my previous comments about how we don't recommend a separate
/var, /usr/local, etc. by default and also needing enough space for
preupgrade.  If they only have 30 GB to work with, we're giving them a
15 GB home.  Is that enough for an installed system, and another whole
system's worth of packages, plus whatever other crud the user may have
laying around?

True, the user could add a bunch of other stuff later.  However, one
good thing about the livecd case is that we know the size of the payload
up front, so we can at least make slightly smarter suggestions.  I'm not
completely sold on this idea yet but it's worth thinking about.
