That's an interesting point. Btw, settrans --recursive is currently
implemented like this, I'll patch this also to use the translator

Actually the code also tracks passive translators being set, but of
course we don't know anything about any previously set passive
translators. Richard and me agreed that for most purposes one needs an
mtab file for (e.g. fsck) it is also interesting to know whether a
passive translator is set and what device it would use because any
user could trigger the translator start at any time.
