Mainly it's a hassle because it adds quite a bit to the build time.

Currently, I change my rootfs far more often than I change the U-Boot
sources or configuration.  Doing a U-Boot rebuild every time I change
my root filesystem wastes a lot of time.

That makes sense.

I guess I'll stick with that.

Thanks.
