I guess it is very common for administrative purpose, to dump and

Though I can not answer OP's question, I have question of my own.
Is this really routine (often) task for Linux sysadmins? I used
something like that to replicate cluster nodes in the past, but
kickstart would be routine task for me. dump/restore sounds like
routine from MS Windows world (I hear they "re-image" system if
something goes wrong ;-)
Am I wrong? Do we in Linux world do this routinely?
I would not say routinely, but I would say crucially.
The poster child for dump/restore is a machine with commercial
software that is difficult to install or customize, especially one
with an RDBMS system large enough to make dumping and restoring the
data tables an onerous task.
The usual workflow -- kickstart and puppet/ansible/etc -- doesn't work
in that situation.
