Comment 1 for bug 301251

This issue has been solved (finally! took me ages to track down the bug), and a fix commited to the turnkeylinux code repository and package archive.
Version: di-live-0.9+1+gnae130b

The fix will be included in all new appliances, and current appliances can update using APT.

For those interested, the bug was due to IFS issues.
    - the user choice (e.g. partition) would not match up internally with the available choices so the choice key could not be returned.
    - by default it would return the RET itself, which would result in a plugin error.
    - the plugin error would result in ask_user returning a failed exitcode
    - which in turn would result in a "No root filesystem" message.

    - bottom line: whitespaces
