Installer: add "whole drive" (anyboot like) install mode

[nephele]

In the "Install to" view an USB drive should be targetable (as in drive itself, not a partition on it), which would then install in a fashion similar to how the Anyboot image is created. This should allow to make portable thumb drives without having to use any workarounds.

Installer would then create a gpt table with MBR, aswell as the iso9660 trick the anyboot has, which should result in a system that would boot of a thumb drive to EFI aswell as MBR/CSM too.

I am a bit confused how this is a duplicate, the other ticket talks about basically redesigning the installer, this one only about adding a target that can be used instead of a partition.

(also this ticket has double the votes, so closing this removes it from the list of top voted tickets)

They are about the same thing: installer should allow to install to a disk without manually creating partitions. I just kept the oldest of the two since there was no reason to keep the new one.

As to wether this is a complete redesign or just am minor change, that's up to the developer writing the code to decide how they implement it. I'm sure they can do it in a simple way because developers know how to do things efficiently and not uselessly rewrite all the app because some person thought it would be a good idea.
