thats not quite true.<br>
yes centos 9 is a roling release but it is more stable then fedroa since packages landing in centos 9 stream have been<br>
stablised via fedroa already and any argurments in this regard would also apply to centos 8 stream.<br></blockquote><div><br></div><div>Stream 8 is part of an already released and maintained RHEL, hence I give it a certain benefit of doubt.

<br>
The only reason that centos 8 stream would be more stable then 9 stream is due to less frequent updates as focus moves to 9 stream.<br>
9 stream is effectivly a preview of what whill be rhel 9.<br>

<br>
why just because rhel 9.0 is relased does not mean centos 9 is sudennly more stable.<br></blockquote><div><br></div><div>Okay, you convinced me, I won't recommend Stream 9 at all :)</div><div><br></div><div>Kidding aside, we know that each major branch of RHEL offers a certain degree of compatibility. It's not expected that 8.N+1 breaks a lot of stuff from 8.N, hence it's not expected that Stream between them will break anything (modulo bugs) either. I have no idea what and how gets into Stream 9 now, nor will I risk recommending it for production.</div><div><br></div><div>Dmitry<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Now that centos 9 has been release there shoudl be no more package removalas form centos/rhel so<br>
it should have stableised in terms of the minium package set and over time we woudl expect more pacakges to be added.<br>
yes centos 8 stream will be supported until the EOL or rhel 8 so people can continue to deploy it.<br>
rhel 9 will be released next year, perhaps not before yoga is released but if you are deploying RDO you will not be useing<br>
RHEL anyway you will be using centos so stream 9 is the better plathform to use if you plan to continue to upgrade the deploy<br>
ment over the next few year as it allow you to avoid the costly OS upgrade when moving to the next openstack relesase.<br></blockquote><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
