Hello All,
I request knowledgeable people to write here broad sequence an openSUSE distribution would follow up to login screen OR point me to relevant resources.
Also, how will this sequence be different between an installed system and a live media booting ?
Is it even possible to combine a latest kernel and an old distribution ? ( Yes, I have such a need )
Thanks in advance
No. It is just booting from the mass-storage device. That you call it a “live media” for some reason does not matter to the system.
Are you referring to Leap 15.6 (as title suggests)?

Sorry for late response.
What I mean is, I have a working installation of OS 12.1 . if I can manage to build the latest kernel on 12.1 ( do not know if possible at all ), other part of the os should have no issue ?
By my logic, it should be possible to build the kernel. But I have no experience. So the question.
Then you should not have tagged the topic (Leap-156) as you did.
openSUSE 12.1 supported 2011-11-16 until 2013-05-15 Kernel 3.1.0.
Twelve years is an eon in computer development. So many interfaces will have changed. Nice hobby. Wishing success.
I believe I was limited by available drop-down tags.
And there isn’t “Other” there?
I will change it to “other” as Henk already hinted at. 
Not hobby as such. Vortex86 industrial PCs do not support later kernels. My systems are Leap 15.6 and Manjaro linux.
I think in this segment ( embedded electronis ) this requirement to tweak an old kernel on modern Linux keeps recurring.
@ deano_ferrari, Thank you so much.
