@Rudolf So Fog can do what you want there’s just a few steps you skipped.
Fog will essentially do the same idea of copying the SSD from one to another but in a more centralized manner with more customization capability.
Basically, you need to
Install and configure the OS on a Virtual or Physical machine (virtual is easier to maintain if you already have a virtual infrastructure) Capture the image of that machine with fog Deploy the image to hostsSee https://docs.fogproject.org/en/latest/capture-an-image and https://docs.fogproject.org/en/latest/intro for some more info.
You can also expand further with customization of how you update your reference image, with windows there’s sysprep and other tools to help create a reference image, I’m sure linux has tools as well, I’m just not as well versed in them.
You can also edit the fog pxe menu to boot to an iso, I’m sure we have some examples in the forum for that.
There are also pre/post scripts so you can have a linux bash script that runs after an image is complete to do further customization of the image.
It sounds like Fog is the tool that will do what you’re trying to do, there’s just a bit more setup.
