It's not the installtion instruction as documented by FreeBSD. I use  
mysql in an ezjail (ports) created jail. It works without any problems.

As the size is printed, there's a real file at the end of the link. So  
my first idea what the problem is, is busted. ATM I have no further  
idea. You would have to "ktrace -i" what the mysql startup is doing  
and have a look at the output (man ktrace, man dump). Then you can  
maybe check that everything what it tries to touch is there.

Bye,
Alexander.
