sorry I sent comment while you are updating this.
toString is slow on where Buffer.indexOf is available. so this would be longer version.

contents = fs.readFileSync('foo.bar');
if (!contents.indexOf) {
  contents = contents.toString();
}

ping @ncopa can you confirm it's ok to cover all Alpine releases or should we look for a wider pattern?

Are you asking whether this test will work for all Alpine releases? If so, yes.

return 'musl';

} catch (err) { }
return ''
