Now I am confused...

which made it sound like the sadump dumpfile format is already similar
to the compressed kdump format.
But this makes it sound like the sadump native-format is unique:

Is this how it would work?:
(1) kernel crashes
(2) sadump creates a native-format dumpfile
(3) (patched) makedumpfile takes the native-format sadump dumpfile and
translates into a format that is similar to a compressed kdump
(4) (patched) crash utility reads the translated sadump dumpfile
Or will the (patched) crash utility be able to read the sadump dumpfile
in its native form if it is not pre-processed by makedumpfile?
