# \brief  Test for 'tar_rom' service
# \author Norman Feske
# \date   2010-09-07
#
# The test spawns a sub init, which uses a 'tar_rom' instance
# rather than core's ROM service. The 'tar_rom' service manages
# a TAR archive containing the binary of the 'test-timer' program.
# The nested init instance tries to start this program. The
# test succeeds when the test-timer program prints its first
# line of LOG output.
#

#
# On Linux, programs can be executed only if present as a file on the Linux
# file system ('execve' takes a file name as argument). Data extracted via
# 'tar_rom' is not represented as file. Hence, it cannot be executed.
#
