I've stumbled into my own confusion here
I was trying to clean up old kernels via MCC and listed the installed
kernels



kernel-desktop-5.15.23-1.mga8-1-1.mga8
kernel-desktop-5.15.25-1.mga8-1-1.mga8
kernel-desktop-5.15.28-1.mga8-1-1.mga8
kernel-desktop-5.15.32-1.mga8-1-1.mga8
kernel-desktop-5.15.4-1.mga8-1-1.mga8
kernel-desktop-5.15.6-2.mga8-1-1.mga8

So I thought , remove the kernels 5.15.23 and 5.15.25 and leave the last
two 28 and 32

But a closer look shows 5.15.4 and 5.15.6
are they more recent?

I would seem to be running 5.15.32
and I believe that I'm confused by the kernel numbering system and the
sort order of MCC, but I'm not sure

Use 'rpm -qa|grep kernel|sort -V", or "rpm -qa --last|grep kernel" which
will show the date installed, with most recent first.

Or check a mirror. http://mirror.math.princeton.edu/pub/mageia/distrib/8/x86_64/media/core/updates/
shows ...
kernel-desktop-5.15.4-1.mga8-1-1.mga8.x86_64.rpm 2021-11-21 13:29 68M
kernel-desktop-5.15.32-1.mga8-1-1.mga8.x86_64.rpm 2022-03-28 09:35 68M

So .32 is newer than .4.

Old kernels and their associated packages such asvirtualbox-kernel are not automatically removed in order to allow fallback if booting a newer kernel fails.

I use the attached script to remove old kernels.

You have sorted the kernel names, but neglected the difference between numerical sort and ascii sort.

Sorted in ascii fashion, 5.15.3... precedes 5.15.4...
Sorted in numerical fashion, 5.15.4... precedes 5.15.32...

Cheers!

Yes I've done all those things. What I find amusing is that in all the previous kernel cleanups I managed to completely ignore the two early kernels. They stand out clearly, obviously and yet I missed seeing them
on at least three occasions.

And despite plodding carefully through the list each time, this is a
stunning lack of observation unless I have some temporary dyslexia I an unaware of.

I had seen David's script in previous posts somewhere.
My script did/does not query rpm like David's does.

My ck_4_kernel_rpms script checks for more than one kernel in /boot with
ls -1h /boot/initrd-*mga* | grep -v $(uname -r) | wc -l
and converts ls -1 initrd-*mga* | grep -v $(uname -r) release into
urpme kernel rpm name(s) and uses xmessage to pop up the list to be removed.

My install_updates scripts runs ck_4_kernel_rpms to tell me to remove the
extra kernels which I do after I have booted the new kernel and verify
I do not seem to have problems.

Note that you can also look at the date of installation of the file
(well the modification time) with
ls -t (newest first)
or ls -tr (oldest first)
instead of alphabetical.cd /boot

I would seem to be running 5.15.32
and I believe that I'm confused by the kernel numbering system and the
sort order of MCC, but I'm not sure

This first time I remember running into this situation was back with
Mandriva. As I recall, there was about 2-3 seconds of confusion before I realized the reason for the way the kernels were listed, but it had been
a long day and I was tired.

Actually, I had remembered installing and later updating the
later-listed kernels, so I knew they were older without looking them up.

My experience with Kernel 5-15-4. has been similar. I am guessing that
it is installed by the OS installer, and for some reason, it doesn't
appear as "old."

They are not removed so that if your new kernel does not work, you are
not left up shit creek without a boat or paddle.
(Actually there is a creek in College Station Tx called Sewer Creek--
runs through the middle of the golf course.)

If you want to remove your old kernels, you can do so. Urpme is your
friend.

Mageia does not remove "old" kernels. However it does put them onto the
orphans list so, if you are silly enough to remove orphans it will be
removed ( It is silly because if one of those "Package" rpms gets
orphaned its removal can destroy your whole system. And they do get
orphaned at times. )
