Why don't developers make installation wizards on linux?

Secondly, there are too many questions that need answers which would prevent there being such a simple set of commands. Things like:
'how much space for Windows, and how much space for Linux on your hard drive(s)?'
'what order would you like the boot options to be in?'
'how many logical drives for Windows and how big?'
'how many partitions for Linux, how big, and where do you want to mount them?'
and so on.
But it never hurts to dream <grin>
