 `roverd` requires access to `/dev/ttyAMA0` and `/dev/gpiochip*`; keeping it under its own user ensures the rest of the system stays isolated—just make sure the account belongs to the `dialout` and `gpio` groups so it can reach the UART and libgpiod.  
 The WHIP publisher needs read access to the camera devices (`/dev/media*`, `/dev/video*`), so the install script adds the `roverd` service account to the `video` group; if you created the user manually, make sure it belongs to `video`.  
 **BRC note:** configure `brc.gpioPin` (and `brc.gpioChip` if you’re not using `gpiochip0`) and ensure the `roverd` user has permission to toggle that line—no root privileges are required anymore.

-The installer builds `ffmpeg-whip` (a WHIP-enabled FFmpeg) from source, installs it under `/usr/local/lib/ffmpeg-whip`, and drops a wrapper at `/usr/local/bin/ffmpeg-whip`. roverd writes `/var/lib/roverd/whip.env` on startup (and whenever you restart the service) so the publisher inherits the correct `WHIP_URL`, resolution, FPS, and bitrate. Tweak those knobs under `media.videoWidth`, `media.videoHeight`, `media.videoFps`, and `media.videoBitrate` in `/etc/roverd.yaml` if you need different camera settings. Building FFmpeg on a Pi Zero 2 W can take 15–30 minutes—let the installer finish before rebooting.

+`/var/lib/roverd/video.env` carries all tunables (`PUBLISH_URL`, resolution, FPS, bitrate). `roverd` rewrites the file whenever you restart it or hit the “Restart Camera” button so the publisher always inherits the correct rover ID + bitrate knobs. Because we now use the distro FFmpeg build with SRT enabled, the installer is much faster—no custom compile steps.
