Sure. For now, deb-log would output to stdout. After the
interactive/non-interactive split, it would output to syslog for the
non-interactive part and output to stdout for the interactive one. If
the user wants it to (interactive_to_log=1 in /etc/deb-log.conf),
it would also log to the syslog.

Also note, that there is no need to change the *inst files a second
time to archieve the splited behaviour (so the change can be
smooth). When the split is done, there will be a way to determine
that a non-interactive setup is run (e.g. environment variable), so
deb-log automaticaly knows what to do.

As long as the installation process doesn't get split, we have to
output everything to stdout and additionaly log it. 

Later, the non-interactive part will output to log and the interactive
one to stdout by default. The user can customize this.

The maintainer has to do the split on interactive / non-interactive,
so he still decides what gets output to which facility, with the user
beeing able to customize the output behaviour.

This is not that elegant as makeing the maintainer mark an output as
stout or log, but forcing a basically equal change two times on the
maintainer is not elegant either.

This is also possible with deb-log, it is more flexible as well, and
it is better preparing for the future.

These are the advantages of my proposal:

 - only one change of *inst scripts necessary
 - prepared for future changes (interactive / non-interactive)
 - transition during the installation split is smooth, will work by
   just splitting the script, no changes to output routines in *inst
 - user has full control over output
