Loukik,
I think we need to lag behind major Linux distributions by at least  
6-12 months
to facilitate installation and adoption. According to my Unix  
Administration
team, several major linux distributions are still at 1.4.  So, I  
don't think we
should move to 1.6 for a couple years unless we have a critical  
functionality
requirement.
