Package: raspi-firmware Hi,
Sometimes it is necessary to add parameters to the kernel command line, for example rpi.gpio requires "iomem=relaxed". In the current setup there is no good way to do this, editing cmdline.txt directly will result in changes being overwritten on the next kernel upgrade. Editing /etc/kernel/postinst.d/z50-raspi-firmware is likely to result in conflicts when upgrading.
