The first solution works well for me as I don't plan on running both
types of servers in production by the time we launch. However, I'm
running into a problem whereby the restart task is calling
restart_solaris and restart_other as expected but both are executing.
For some reason the :except seems to be ignored. Is there some way to
turn on debugging output to figure out what is going on?
