Could you please provide a simple Buildroot .config that exhibits the
issue ?

Why "as expected" ?

Why would you do this? It should have been installed by util-linux.

When reporting bug reports, please always include a Buildroot .config
file that allows to reproduce the issue. Also, make sure that the
problem is reproducible after a full clean build, i.e when doing "make
clean all".

Thanks!
