A dnf upgrade to 7.1.8 installed the kernel rpm cleanly, then ran /boot out of space. dracut wrote no initramfs, and because kernel-install stops at the first failing plugin, 95-c630-devicetree never ran either — leaving a boot entry with neither an initrd nor a devicetree line, which on this machine can never boot. dnf reported success and nothing retried. A kernel costs ~336 MiB here: a 210 MiB hostonly=no initramfs, a 98 MiB dtb-<kver> directory carrying every board's device tree, plus vmlinuz and System.map. Three of those cannot fit 1 GiB, so /boot goes to 2 GiB and installonly_limit drops to 2. Also fixes the quieter half of the same trap. snd-soc-wsa881x lives outside the kernel package, so the speakers go silent after any kernel update with nothing in the logs to explain it. c630-wsa881x rebuilds it and 96-c630-wsa881x.install calls it on each kernel-install add — always exiting 0, since a plugin failure is precisely what caused the damage above. grub.cfg gains the next_entry one-shot block that has been carried by hand all along, so testing a kernel costs a power cycle rather than a rescue.
