Understood.  That's why I wrote it the way I did.

Over the last few years, FreeBSD and MySQL have stopped working
together as well as they used to.  We recently saw a (single) customer
with crashes that we haven't been able to analyse, because they only
occur on their production system.  It looks as if the "solution"
chosen by customer management (against strong resistance from the
techies) is to move to Linux.

This kind of issue, but also performance differences, are a
disadvantage for both groups.  One of my tasks at MySQL is to do
something about that, but I'm spread pretty thin.  If anybody has
input on this kind of topic, I'd be interested to hear from you.
