Hello All,
I guess it is very common for administrative purpose, to dump and restore a CentOS 7 system.
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?
You are not wrong. However, I will point out first that dump and restore are utilities that have been around the Unix/Linux world for a very long time, rather than something from the M$ world.
The issue of how to restore/copy a system installation is open to discussion these days. I have recently been in a situation where duplicating identical machines is done conveniently with dump and restore. I have also been in situations where installing or reinstalling a system of slightly different configuration is easily accomplished via kickstart.
It mostly depends on the situation to be addressed at the moment, and the tools available. For instance, to perform a one-time installation when you do not have kickstart set up on your network is a significant amount of work, and may not be worth the effort of kickstart set-up.
This is one of the benefits of decades of development. More tools are available to handle the installation requirements.

I usually use dump/restore commands. However, I’m having trouble to handle installing bootloader and creating initramfs for C7 system. Does anyone know a good document source that details those procedure? Thank you,
