I spoke to Heinz on the Linux kongress and we already were
searching for solutions to this to let newbies install
a linux with swap and different filesystems into one
partion, so you dont need to care on filesystem sizing etc
on installation time. You might insert a cd .. which asks you
for the real partition and the disk and then installs happily
reboots and then you might install packages and the
filesystems will grow as you need ...
There will be solution but as the architectures are so different
we will have to have multiple solutions to this.
