Thanks, yes, it does sound weird and will double check for any pebkac issues, too.

Oracle EL is definitely on the list, will check it, as well.

I wish they stuck to software collections, really.


Both solutions have had significant 'user' and 'developer' pushback. Many groups (developers, users, customers, IT groups,etc) complained about how bad SCL's were and asked for changes that were then implemented into modularity. I find it sort of like a 'Beware of what you complain about, someone may try to fix it.'

Thanks both.

This is what I saw in that particular Rocky installation: https://pastebin.com/raw/bKnFMM9a

But I'll do a fresh comparison between all clones as soon as I get some time and try to get to the bottom of it.

 
OK, that is weird. It is showing each past 'version' like it was completely different. I am wondering if there is some sort of dnf config option in play here. It might be possible to set up dnf to not see each version in a stream as different enough so you could 'hard swap' between them versus let them update continuously.. something like
RHEL/Alma config: compare stream and update to newer version of any release
your system: compare stream:version and only update if forced with a swap.
 
I would check with Oracle and see how they are doing things also.

Hello,

We've just been bit by some libvirt updates in our project (Apache
Cloudstack) which basically broke basic functionality on AlmaLinux 8.4.
I expected the same problem to happen on RockyLinux 8.4, however turns
out the libvirt on this one was an older version and not even "yum
update" changed this.
On closer investigation I noticed Rocky actually ships 5 "virt" modules,
according to "yum module info virt", my Alma test box only ships one,
which is also very up to date.

No actual complaints here, but can someone explain to me why the
discrepancy? Didn't use EL8 much, but expected all "clones" to be more
or less identical, but turns out there are differences that matter.

 
Hmm I do not know what is going on with the Rocky side of things, but I am guessing there might have been a mismatch on how to build module 'versions' as module 'streams'. Let us look at perl and virt as examples. RHEL offers 4 perl streams with different lifetimes and support leveles ( https://access.redhat.com/support/policy/updates/rhel-app-streams-life-cycle ) and only one  virt stream.

The virt module has had multiple versions over its lifetime with RHEL-8. The EPEL build system accidently keeps a list of them due to grobisplitter putting them into trees when they are first seen.

To a user you should see only one module stream which is virt:rhel. It should then continuously get updated when the 'version' of the module is updated and all the packages in this 'pseudo-repository' are updated en-mass. I do not know how Rocky has split things up and it could be for multiple reasons like they are offering alternative streams or their tooling at one point split things in different ways than RHEL does.
