I've tried to do that in the past when you've asked about it previously,
but it always fails in testing for me. When I tried to understand why,
it seemed to be some shell subtlety that involved variables set inside
subroutines not being global in some cases. I've tried it again and
gotten the same results. If you could perhaps suggest a patch I'd be
happy to test. I've attached the patch I used. Here's what I had in rc.conf:

mysql_proxy_enable="YES"
mysql_proxy_backend_addresses="127.0.0.1:3306 127.0.0.1:3307 127.0.0.1:3308"

Unfortunately, with this change, the backend addresses were not passed
to the daemon as args.

Steve
