Using label-based booting makes this issue go away: https://salsa.debian.org/raspi-team/image-specs/-/commit/f89f71560d2ca1bd60d97dbb26b89782657d56ae Before this commit, the first few boots would happen with a label-based booting, but that would go away as soon as the raspi-firmware hook would run, leaving you to get either mmcblk0 or mmcblk1 at boot-up. I only observed that on the Pi 4 family (Pi 4 and Compute Module 4), and I'm not sure this is directly linked to the Linux version. (I've had a lot of back and forth due to heavy debugging so I don't recall coming to a conclusion for that one except “use labels, always”.)
