It would be nice to be able to be able to save the selections such as ip addresses, selected packages etc to /dev/fd0 before the install starts. (There are a LOT of selections!) That way it would be easy to duplicate the same install if something goes wrong or similar configuration (package selections) would be needed on a second machine. Even a raw dump of the variable space in question to some disk sectors would be ok - the disk doesn't need to work across different distros and imho, needing a blank disk to do this is justified. It would be AWESOME to be able to preload the anaconda selections from a floppy and then use the [Next] button to go through the data and change just what is needed. But even a 1:1 duplicate would save a lot of trouble when repeating a failed install.
Unfortunately, it's too hard to save state in a really useful fashion and floppies are also fairly obsolete at this point. At this point, not really going to do this.
