To me, it seems odd to have translators fiddle with their stdio in
that way. Why not simply let the processes send messages to their
stderr, and redirect stderr anytime you want to? I.e.

  settrans -a foo /some/translator 2>/dev/console

(I'm not sure about the passive case, you could use

  setttrans -p foo /bin/sh '/some/translator 2>/dev/console

but it seems more straight forward to set the parent file system's
stderr to where you want it, and let child translators just inherit
it).

Why was this feature added to libdiskfs? I agree that some consistency
would be nice.

I also suspect that some people would want all messages to go via
syslog, but I don't know enough about that to say if that would be
useful.
