Currently the installer loops through block devices giving a y/n prompt at each one and installing to the first device you input y at. Instead, it should give a list of devices that can be installed to, and the user selects one.
Now in oe-core, see commit e68774f684543fd75250e56ea88a5e0cb0a2dd0a.
Verified on genericx86-64, installlation menu is displayed correctly.
