In TEXT mode installation we have 'us' keyboard preselected instead of 'cz-lat2'. The graphical installation is OK (keyboard mapping is not 100% OK but still acceptable).
verified ... this behavior only occurs when selecting language/keyboard during stage2 (selecting language/keyboard during stage1 does properly associate language w/default keyboard selection)
fixed internally ... ready for QA to verify
verified fix in internal build ... thanks for your report!
