* Internal modules return only their own errors. All downstream errors are converted. In this case, the module needs to check only N-1 level errors. * Do not convert errors from internal functions. They must return the correct errors. * When converting an error with loss of context, it is necessary to write the previous error to the log. Signed-off-by: Gladkov Alexey <agladkov@redhat.com>
