In an X session stderr is ~/.xsession-errors which I think is right.

For console apps I think keeping stderr open is likely correct also.
If there are errors they should be seen, and they will not interfere
with normal command output (that is why it's stderr and not stdout).

stdin/stdout, I don't know. I can't think of anything dbus-daemon does
with these, which probably means it doesn't matter what they point to.
