- Fix access to potentially undefined data structure

  * wait for the recovery partition device to appear
  * use a journaled (ext3) filesystem for the recovery
  * wait for the root device to appear
- Fixed createFilesystem boot code function
  * make sure btrfs creation uses -f option to force creation
    of filesystem even if another fs exists
- Fixed error handling in recovery mode
  * the progress information is shown by the continous output
    of a sub process of the calling shell. The sub-process has
    no access to the controlling terminal thus calling system
    exceptions there cause a hangup of the process at that
    stage. This patch fixes it by not calling exceptions and
    handling the result exit code of the sub-process outside

  * Use grub2-install with correct options instead of
    raw calling grub2-bios-setup

  leading to a Use of uninitialized value $2 in concatenation
  error
- DB: update documentation
  + add information about installpxe option in the man page
  + make it more clear which file is expected to the --install*-system option
- DB: rebuild documentation
