Hi, on latest master of util-linux, there's currently 20 test- and subtest failures on musl based systems. There's three different categories of failures: - Reliance on buffering properties of stdout/stderr. - Expectance of non-standard error messages returned by strerror(3P). - Expectance of EILSEQ with POSIX locale. This patch set fixes all of the above, bringing down the number of failures from 20 to a single test failure. The remaining failure is in getopt(1), which documents and implicitly relies on the POSIXLY_CORRECT environment variable when calling getopt_long from glibc. Adhering to this variable isn't implemented by musl libc, so to get this working correctly one would have to modify getopt(1) itself, e.g. by automatically prepending a '+' to the optstr if the envvar is set. But I'll leave that to another patch series.
