This impacts all arm64 installs, not just raspberry pi. The MIR for qrtr and protection-domain-mapper [0] was requested late in the Mantic cycle and was only approved by Security since it was promised to only be used for x13s hardware enablement. Hopefully Qualcomm IPC is only enabled for x13s kernels.
As noted in the qrtr MIR: > We should be cautious of IPC routers running root permissions. Similar code > has > enabled vendor backdoors [1]. Furthermore, qrtr has nearly no documentation and has no inline code comments [2]. Please remove this from the mantic and noble's ubuntu-meta package.

However, there's no hardware that they target on these platforms, and the result is a permanently failed service (pd-mapper.service). It appears these were added to support the X13s laptop [1]. I've attempted to work around the issue by excluding these packages in the desktop-raspi seed (experimentally in my no-pd-mapper branch [2]) but this does not work (the packages still appear in the built images). Ideally, these packages should be moved into a hardware-specific seed for the X13s (and/or whatever other laptops need these things). Alternatively, at a bare minimum, the package should have some conditional that causes the service not to attempt to start when it's not on Qualcomm hardware.
