[Freeswitch-users] Tuning Up Freeswitch

I would hardly call directing users to a stable distro "quite short sighted"
considering we run on mac windows bsd solaris and most any linux, I fail to
see any short sightedness.

In fact we have a guy who maintains ubuntu packages and another on arch.  In
fact I just got a new bleeding arch box and got very good results.  The
latest fs works well on both old and new distros.  I would venture to say
that perhaps you are the short sighted individual, reading too specifically
into one aspect of our development.   I will continue to recommend centos to
new users until they gain experience and have the skill to use the distro or
os they want.
