   With `runqemu qemux86-64 qemuparams="-m 2048" core-image-ros` the linux image runs within a virtual machine with 2048 MB of memory.
   We assumed that this is running on and compiled for an x86-64 architecture. For other architectures, some settings must be adjusted.
   
-  Extract ros_server.tar.gz somewhere, adjust pathes in fuerte-ros-base.rosinstall to the location where it has been extracted to.
-  After starting the virtual machine, copy the installation script from the guest system to the home directory with scp and execute it.
+  On the host system, run fetch_ros.sh in a fresh directory, e.g. ~/ros-repos/.
+  It clones all ros repositories locally.
