Yeah, I guess we could (except for exec maybe).  The stroy is that we don't
do it for all system translatores right now, which means that what they have
to say to us gets lost.  The motivation of Moritz was that he debugged
pfinet, which got an assertion failure.  If pfinet had its output redirected
to the console, this would have been trivial to see.  But he could only find
out with gdb what's going on.

Yes, that works. (except for the single quote)

The root filesystem can not access /dev/console until after the bootstrap
has happened.

We discussed this earlier here on the list, it's a TODO item (syslogify
everything).  I forgot the results of the discussion, though ;)

Thanks,
