| Tested | **Reliable in-place upgrades** | Force GRUB bootloader with `--no-nvram` on arm64, handle SBC EFI-only disk layout. Verified end-to-end with `talosctl upgrade`. | | Tested | **Reliable in-place upgrades** | Force GRUB bootloader with `--no-nvram` on arm64, handle SBC EFI-only disk layout.

## NVMe boot (untested) ## NVMe boot
The kernel has NVMe built-in (`CONFIG_BLK_DEV_NVME=y`), so booting from NVMe should work by flashing the disk image directly and configuring the RPi5/CM5 EEPROM.
