I don't know RDS at all, so please take what I say with a big grain of salt.
That said, the sysfs approach is pretty straightforward and has worked well
for us. One thing which we didn't do (yet) but maybe useful is defining some
conventions to tell whether a given feature or option should be enabled by
default so that most users don't have to know which features to use and
follow whatever the kernel release thinks is the best default combination.

Thanks.
