I'm having a similar problem starting MySQL from the LiveCD. I've tried using the mysqlmanager and I get an error that it can't locate mysqld, which makes sense because this does not appear to exist on the CD. Is this an incomplete installation of MySQL or is there some post-burn configuring that needs to be done?

I also thought the LiveCD had postgreSQL capability, but I haven't been able to run that either---am I mistaken?
