During Cauldron update this morning, got this twice:

Code: Select all

I get the same error with or without '-o loop' on mount.

How dangerous is this?

There's a pretty old bug report about this: https://bugs.mageia.org/show_bug.cgi?id=19049
It can be ignored.
You could try to regenerate the initrd via dracut to see if that helps, as root:

Code: Select all

dracut -f

Sorry if I'm being overly cautious; but this "error" is complaining about 6.6.50 which is next to boot vs currently running 6.6.43

Code: Select all

$ dracut -f
returned lots of "because command '...' could not be found!"
and finished with:
dracut: *** Creating image file '/boot/initrd-6.6.43-server-1.mga10.img' ***
dracut: dracut: using auto-determined compression method 'pigz'
dracut: *** Creating initramfs image file '/boot/initrd-6.6.43-server-1.mga10.img' done ***

which is the running now vs 6.6.50 which is on deck for the next reboot. initrd is critical to boot; hence my caution.

You shouldn't be running cauldron if you're overly cautious, see my signature. I don't even understand what you're so cautious about - it there's an issue, just select the previous kernel from the bootloader.
What will you do if there's an _actual_ issue and not only some informational message ?

For dracut you need to specify the initrd version if it's not matching the currently running kernel. See e.g. https://forums.mageia.org/en/viewtopic.php?f=8&t=6433 for an example.
Or use dracut --regenerate-all to regenerate all of them.

And regarding „missing modules“. That are status messages and absolute basics. Have a read here:
