I wonder if it might be helpful to keep the silentoldconfig target for a
while and have it just fail with a message like the following:
silentoldconfig has been renamed to syncconfig and is now an
internal implementation detail. What you probably want is
oldconfig.
Going on Google and https://lkml.org/lkml/2018/2/12/1084, there might be
quite a lot of scripts and the like that call silentoldconfig.
Alternatively, it could call through to syncconfig and also generate a
warning that it's about to removed (like for olddefconfig).
Cheers,
Ulf
