Series | runqemu: Add QB_KERNEL_CMDLINE | expand |
This means QB_KERNEL_CMDLINE needs to be set by default everywhere to preserve existing behaviour, I'm not sure this is going to work. Can you achieve the desired effect with a reverse condition?

Right, I still find the naming confusing though. Can it be QB_RUNQEMU_KERNEL_CMDLINE_SUPPRESS? The name needs to indicate that it does not contain the actual cmdline, but only a flag to suppress it.

Right, that's ok then, although the naming for both could be improved.
