Hi!
A bit of history first: my Fedora, then (after reinstall) my openSUSE
then (after reinstall) my Gentoo failed during boot. I thought it was
something related to dracut so I've been adding `hostonly = false` to
dracut.conf on all my home machines.

In summary, yesterday it failed on my Gentoo so I had to investigate.
* I had enable `unstable` use flags for the kernel only.
* I hadn't double-check the boot entries created.
* Power went off (no UPS yet) so I booted the new kernel.
* It didn't boot. I fixed two things: changed the partition id of
LUKSed swap from swap id to LVM id, to prevent systemd attempting to
mount it at boot (and failing). Secondly, I checked the fstab and
noticed all dev nodes were wrong (I have two SSD).
* After fixing the dev nodes in fstab the system booted properly.

This probably explains the Gentoo failure, since other distros (and
me, starting some day) use UUID in fstab.

So, my question is:
Has anyone any input on mysterious failures across several distros,
including Gentoo, around kernel 6.9.x <> 6.10.x?
