- thermald on the x86 hosts (guarded; the Asahi MBP self-governs). - T400 battery charge thresholds (75/80) via tp_smapi; tlp itself comes from the nixos-hardware profile. - Bluetooth (bluez + powerOnBoot) and blueman on the laptops — the MBP already loads Apple BT firmware but bluez was never running. - earlyoom + fwupd on the physical graphical hosts; zram on the Mac Pro.
