Simulating an upgrade — running kernel-core's %posttrans command by hand —
turned up two faults that had nothing to do with the full /boot, and would
have broken every future kernel install on their own.
95-c630-devicetree trusted $KERNEL_INSTALL_BOOT_ROOT. `kernel-install inspect`
reports "Layout: other, Boot Root: /boot/efi" here, because the ESP is all it
recognises, while Fedora's 20-grub.install writes BLS entries to
/boot/loader/entries regardless. So the hook looked for the device tree on the
ESP, did not find it, and skipped the patch — leaving an entry with no
devicetree line, which on this machine cannot boot. Paths in a BLS entry are
relative to the filesystem holding the entry, so the only correct boot root is
the one carrying both loader/entries and dtb-<kver>. Search for that instead.
dracut-config-rescue sets dracut_rescue_image=yes, so each install also built
a second ~210 MiB initramfs, which is what refilled /boot straight after it
was cleared. That image cannot boot this machine either: the rescue entry is
<machine-id>-0-rescue.conf, carrying no kernel version, so the devicetree hook
never matches it. Turned off.
Verified by rerunning the simulation: both kernels now have a devicetree line
and a present initrd, no rescue image is generated, snd-soc-wsa881x is rebuilt
automatically, and /boot holds at 72%.

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.

Assembles a ready-to-write disk image via Gitea Actions. Mainline has carried
sdm850-lenovo-yoga-c630.dts since 5.5 and Fedora ships it in kernel-core, so
unlike aarch64-laptops/build there is no kernel or GRUB to compile — what is
left is producing an image that boots on firmware which hands Linux no device
tree.
The build runs in an aarch64 container under qemu-user and builds filesystems
from directory trees with mke2fs -d and mcopy rather than mounting loop
devices, so it works on runners that will not hand out /dev/loop-control.
A kernel-install hook writes the devicetree line into each BLS entry; without
it the first `dnf update kernel` would produce an unbootable system.
