Set root password to specified/generated ssh password. When using Grml as a rescue distribution for dedicated server it is typically necessary to change the root password manually as user expect to be able to login into the rescue system directly as root. This patch modified the behaviour of the ssh bootoption and will set the root password to the same value as for the grml user.
Support 9p-virtio filesystem for mounting the DCS-directory. This patch allows to use exported directories via 9p-virtio to be used as DCS-directory. This allows customization of standard Grml ISO images in virtualized environments without the need to adjust anything or create specialized blockdevices/floppy images. For a short introduction about using 9p with qemu/kvm see http://wiki.qemu.org/Documentation/9psetup
Re-add simplifed support for brltty. If a brltty option is specified at the commandline run brltty.sh brltty reads /proc/cmdline itself so there is no need for running brltty with the specified bootoptions. http://mielke.cc/brltty/guidelines.html documents the boot option.
