Yes, I agree, the user mode emulation should probably be removed. It
simply cannot work properly, because we have no way of guaranteeing
that the kernel headers used for the target toolchain are older than
the kernel running on the system.

And even if we want to keep the user mode emulation, I think there
should be one single package. Nothing prevents from having sub-options
to enable either the user mode or system mode emulation, or both, or to
have a version selection.

Best regards,

Thomas
