Ah, ok, seems we are abusing that $LOG... stuff for running fai-chboot as well.
Not really nice, IMHO. Would you mind filing a bug with the Debian BTS about his
issue? I bet we're not going to get this fixed within the next days and it would
just get lost all too easily.

I'm not sure whether we want to fix those "problems" at all - none of them will
be causing problems for the installed system, doing a redirect to /dev/null
would be just as good.

Best,
