Yes, kinda.
I think I'll check if a FileLogger exists, then print to syslog or tasklog.
The thing is I don't know if I should keep it simple and merge everything
in a single layer, or if I should do the check in the Filters (of which 
there are
two, one for each layer).
If we merge it into a single layer, it's easy and fast, but it's not 
that clean
anymore, we can't reuse the single layers etc..
If we keep them separated, we have to check twice if the FileLogger 
exists (in each filter)
(it's probably not so expensive, but still) but we'll keep the 
FileLogLayer and the
SyslogLayer separated and clean.
What do you think?
