known issues

• The installation isn't fully unattended. Because of unknown reason is this not possible. There must be minimum one command uncommented.
• The computer restart directly after the installation. So if the bootpriority of USB-devices is higher then the priority of the HDD, the computer could end in an endless lopp of installations. At the moment of the action to continue the installation will be shown, if there are other installed operating systems.
• The language and the keyboardlayout are set to english and en_US. These things are individualized after the installation is finished.
