Perhaps the "zfs" package can be split in an userspace package (containing
userspace binaries and libraries) and a kernelspace component (containing
the kernel module)? And let the kernelspace component be unsubstitutable
and the userspace component substitutable?

If so, GNOME users won't have to compile ... unless they also use the
kernel module of course.

Or do the licensing concerns also apply to the userspace component?
