journal is already good logging infrastructure under systemd system. But
the centralized logging is very heavy if there are many logging
messages. I know, we should reduce the log messages. But it is really
hard on short development lifecycle product. We should fix many problems
with many logging message. I think, this can correspond to many of
embedded system. By this reason, in Tizen, dlog is still main logging
system.

I'd never want to blame systemd journal logging. That just does not suit
on our system(Tizen).

Anyway, I think text file logging itself can be useful even if we can
see the log from systemd journal for debugging or many other purpose
such like shell redirecting.
