When SYSTEM-KERNEL-ARGUMENTS? is true, add kernel arguments such as '--root'
and '--load' to the returned file (since the returned file is then usually
stored into the content-addressed \"system\" directory, it's usually not a
good idea to give it because the content hash would change by the content hash
being stored into the \"parameters\" file)."
