[Error Msg] ++ set_initrd ++ initrd=initrd ++ cat <<< hang here
[Root Cause] Function set_initrd() have follow line: cat $initrds > $initrd
when $initrds is null, the script will hang when execute cat command.
[how] before: firstly, `cat $initrds > $initrd`, secondly, `[ -n "$initrds" ] || exit` after: directly use `[ -n "$initrds" ] && cat $initrds > initrd || exit`
