[why] If a HW machine has no physical volume or volume group for logical volume, we should support to create them by job param, this param named as pv_device(default empty and do nothing). If a usable $pv_device is given, dracut will check the device and ensure pv and vg. Usage: submit job.yaml ... pv_device=/dev/sda

you should avoid to nested "if condition", perhaps [ -z "$pv_device" ] && return [ ... ] || { } Thanks, Liushaofei
The logic is only if $pv_device is given, it will do some create operation, if not, it will skip and go on instead of return.
Thanks, Xijian
