The package installs a multi-user.target.wants symlink, but that alone does
not survive image build: pmbootstrap runs systemctl preset-all, which removes
manually-installed .wants links for any unit whose preset does not enable it.
The 2026-08-24 image therefore shipped the service as
'disabled; preset: disabled' and it never ran, so aw88261_acf.bin was never
extracted from the stock vendor partition and a fresh install came up with no
sound card at all.
Reproduced and verified on the dev phone: with no preset file installed,
systemctl preset leaves the unit disabled; with it, the unit comes back enabled
and stays enabled across a full preset-all.
Investigation and evidence: fp6 repo journal/blobs/, 2026-08-28.

New package fp6-vendor-blobs: a manifest-driven systemd oneshot that
copies proprietary blobs out of the stock Android partitions on first
boot. pmOS installs flash only boot+userdata, so every installed unit
still carries the stock vendor/dsp partitions - the device duplicates a
file it already contains, for its own operation, and nothing proprietary
is distributed by us. Partitions are mounted read-only (ext4 additionally
with noload - not even a journal replay touches the stock data), every
copy is sha256-pinned and a miss fails loudly, and the consuming devices
are unbound and re-probed afterwards so the feature works the same boot.
The rebind is unconditional by design: aw88261 binds on a bare i2c
chip-id probe and requests the ACF only at ASoC card init (~21 s, after
SoundWire enumeration), so a bound device can still be one that lost the
firmware race - and that failed request is never retried.
soc-fairphone-fp6-audio (pkgver 4) stops shipping the blob, installs the
manifest fragment instead, and re-runs the extractor from
post-install/post-upgrade so upgrades restore the file immediately (the
old package version removed it on upgrade). License drops back to plain
BSD-3-Clause - nothing proprietary left in the package.
Verified on the dev phone (fp6 repo journal/blobs/captures/
2026-08-24-first-boot-extractor-verification.txt): first-boot extraction
+ same-boot audio, mid-session post-upgrade recovery, and the everyday
fast-path no-op; committed files byte-identical to the tested deployment.
