Research direction
The issue points to a Codecov report for src/uu/who/src/platform/unix.rs. Start by examining that file on GitHub and the Codecov link to see which lines are uncovered. Then write tests for those uncovered branches or logic, following the existing test patterns in the same directory. The issue comments may provide additional hints on which parts are easy to cover.
