Default FS Layout Too Small?

I noted that if I choose the auto defaults for my F/S layout, sysinstall
will not reserve enough space for root(512MB?).  This is just barely
enough to recompile and install an updated kernel.  Much more than that
and the F/S is full.

I would assume that the default would be much larger now-a-days. I think
a simple doubling to 1G would be sufficient.

Comments?
