## defaults for module install_mars
##
## installs the mars module on given hosts.

## install_mars_method_list
##
## array containing provided methods to install mars on a given host.

## the variable install_mars_method contains the currently chosen method.

## method kernel_and_modules_via_sync_from_host_to_host
##
## installs kernel and mars module from given (source) host on the target hosts
##
## it is assumed that the kernel and the corresponding moduls could be
## identified on the source host by a string (e.g. 3.2.41-generic). This
## string is saved in the variable install_mars_kernel_release
## it will be checked that there are the following files and directories:
##
## /boot/vmlinuz-<kernel name>
## /boot/System.map-<kernel name>
## /boot/config-<kernel name>
## /boot/initrd.img-<kernel name>
## /lib/modules/<kernel name>
##
## userspace tools (see install_mars_userspace_src_file_list are copied to
## directories install_mars_userspace_target_dir_list on every target host
