Hello @fbq815, can you explain more? I see 9dadd01 mentioned s390x usually uses /dev/dasd* devices to boot from, but not you change to common value sd*, all composes match this? Or only the newest? How about (?:da)?sda[\d]*.

>>> re.findall('(?:da)?sda[\d]*', 'sda1')
['sda1']
>>> re.findall('(?:da)?sda[\d]*', 'dasda1')
['dasda1']

double check with developers that before z13 we only have dasd as the system disk, updated thanks for highlight!
