I am more interested in knowing the how the for example operating
environment is detected
for example using AWS.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AMIs.html

I would like to know more than what is given in the above link as
certainly I should be able
to configure an instance.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/UserProvidedKernels.html

The above link gives how a custom linux kernel can be used. But my
question more to anything
other is what are dependencies for example I move from Linux Kernel
version 3.0 to Linux Kernel
version 5.0 what is the guarantee that the Image generated is correct.
Does AWS imply that unless
Amazon Certify the 5.0 Kernel It cannot be done.
