Read Only Data Directory

[Jake Peavy]

Hey yall,
 I'm trying to use a DVD (containing a number of packed MyISAM tables in a
directory) as the datadir in my my.cnf but I can't start the server: mysqld
is trying to write to the datadir - error log, etc - and when it can't the
server craters.
 Is there anyway of using a readonly directory as the datadir? Are there
other options I can specify in my.cnf where I can tell mysqld to write the
error files/etc?
 TIA,
Jake
