lys@crystal ~/compass-ci/providers/qemu% cat --help cat Copy standard input to standard output.

when input is null, script will hang to waiting for input.

[how]

function set_options(): cat $initrds > $initrd

before: execut cat command, then check after: check kernel, check initrds, if not null, execute cat command.

in addition, check_option_value -> check_kernel, check_initrd, check_qemu convenient to call as needed.
