Can't select which drive to resize when using "install alongside" in Trusty

[Erick Brunzell]

Just following up on bug #1260473 and in addition to not being able to resize the selected partition you can't select which drive to use if more than one drive exists if using the install alongside option.

However, with the same installation media, I can choose which drive to use if using the entire disc option so I suspect the two bugs are related or perhaps even duplicates.

I filed duplicate bug #1298311 in hopes that a simpler drive configuration would make it easier to reproduce this ........... just saying :^)

This is likely a duplicate of bug #1240622 or vice versa.

Yes, the underlying resize_use_free implementation in partman-auto has only ever supported selecting a single disk. To fix this, it would be necessary to refactor it to work something like some_device (so the choices script would only check that it can work at all, while the do_option script would offer a selection of the relevant disks), and then ensure that ubiquity still works with the amended flow.
