I tested both boot and non-boot device as dumping target, and it works
on beaker machine.
But how does it work? suppose rd.* param are mandatory, who will pass it to 2nd kernel?
Suppose below case:
rootfs: a local scsi disk sda
after bootup, one can setup a non-boot disk for kdump ie. sdb.
There should be nothing in boot param.
