I have a read-only SD card, so I’m not worried about the Pi, but it does have the unfortunate side effect of making the backend stay awake for 2.5 hours after the TV is turned off. If the backend turns on to record it shuts down two minutes after the recording finishes.

Thanks for linking me to that ticket. When and why the backend decides it’s safe to shutdown is unfortunately very opaque.

I did see that message, but my set up is pretty different so I didn’t respond. I’m actually network booting, so the sd card is read-only because it only contains the kernel and a few supporting files, but the actual file system is read/write. I did manage to get true network booting working, but it was to unreliable. Using the sd card to kick start the network boot is much better.
