[Error Msg] ++ set_initrd ++ initrd=initrd ++ cat <<< hang here [Root Cause] Function set_initrd() have follow line: cat $initrds > $initrd When there is no job corresponding to current vm in the remote redis queue, var $initrds will be equal to "". And from `cat --help`, we can know the follow: cat Copy standard input to standard output. So the process will get stuck waiting for input. [How] Function check_option_value() is used to check whether $initrds or $kernel is empty. And $initrds and $kernel are assigned in the function parse_ipxe_script(). So move check_option_value() before set_initrd().
