What will happen to your system when/if there is new kernel change every few days? How much "punishment" can your system handle safely?
You certainly control when you can and want upgrade your deployment systems. It has nothing to do with the cadence of updates coming into a distribution.
I find this fixation on the kernel updates is skewing things a lot. Kernel, certainly, is important, but it is not the thing that is RHEL or CentOS distribution, alone.
It is crucial issue if you install any kernel module not provided by Red Hat (3rd party drivers). If some software that you might or might not use brakes, you can mess around your working system and fix it. But if after dnf update your system crashes or network is down, and it is bare metal system, they you are f**ked, you need to reach the system manually (I install on regular PC hardware without ILO) and reverse to prior kernel. Even if I am quick about it, it will be very embarrassing for me in front of my clients (small in number as they are) whose work will stop for that period, so I will not be caught dead using CentOS Stream, I do not need the potential headache, embarrassment.
That's pretty obvious with any system, really, no need to repeat that. I think this topic was raised multiple times (by you and others already) to realize that. In an ideal collaborative world, perhaps, those 3rd-party drivers could be build and tested automatically on top of the CentOS Stream, though we are yet to reach that point of collaboration.
Seams it IS needed since you think it is not that important and I think it is crucial. When you dismissed it so easily as irrelevant, I thought you were not informed.
Following your approach to a detailed information about the Stream, we've been told there are various RHEL subscription programs coming next year that would address use of RHEL for many existing CentOS users. Perhaps, those programs would address the needs of consumers of 3rd-party drivers too, before we'd reach the collaboration ideal I outlined above. Let's see how that goes.
So you think Red Hat will offer no-cost subscription to a small 5-10 employee company, not in any way related to education or non-profits, that needs 1 CPU / 16-32GB RAM Linux server for mdadm RAID10 + Samba + KVM ?
