Sonnet pre-deployment review caught a BLOCKER: on a fresh higgs
(Debian 13 / Pi CM5) install without the RPi kernel headers
pre-installed, the postinst's `dkms autoinstall || true` silently
swallowed the build failure. Package appeared installed but the
.ko was absent; `modprobe daedalus_v4l2` then failed and the
entire stack was dead with no clear pointer to the cause.
Fix in both ecosystems:
debian/daedalus-v4l2-dkms/build-deb.sh:
- After `dkms autoinstall`, verify the post-condition with
`dkms status -m daedalus_v4l2 -v VER -k $(uname -r)`.
- If the module isn't 'installed' / 'loaded' for the running
kernel, emit a yellow-bolded ANSI warning naming the most
likely cause (kernel headers package missing) and the exact
recovery steps (linux-headers-rpi-2712 for RPi or
linux-headers-$KERNELVER for Debian generic, then
`dkms autoinstall` + `modprobe`).
- Colour only on TTY; the warning is unconditional regardless.
arch/daedalus-v4l2-dkms/:
- New daedalus-v4l2-dkms.install with post_install +
post_upgrade hooks that run the same `dkms status` check.
- post_upgrade catches the case where a kernel-headers package
was uninstalled / pruned between upgrades, silently
regressing the build.
- Wired into the PKGBUILD via install="${pkgname}.install".
Both versions point at the actual repair commands rather than
just saying "build failed", so the user is one apt/pacman away
from a working stack instead of debugging dkms internals.

# daedalus-v4l2-dkms — DKMS package for the daedalus_v4l2 out-of-tree
|
|
# kernel module (V4L2 stateless decoder shim for Pi 5 / CM5).
|
|
#
|
|
# Pair to daedalus-v4l2 (userspace daemon). When loaded, the module
|
|
# registers /dev/videoNN (V4L2 m2m) + /dev/mediaNN (media controller) +
|
|
# /dev/daedalus-v4l2 (chardev to the userspace daemon). Userspace
|
|
# clients drive the V4L2 m2m + request API path; the daemon does the
|
|
# actual FFmpeg-backed decode on /dev/daedalus-v4l2.
