Hi Andrew, the description Dirk gave is accurate. We use a RAM disk to copy the Postgres Database to and start it from there.
If you want to run OpenACS from your harddisk, you should just copy the pgsql files from the disk over to your harddisk as well as any AOLserver and /web/ directories. But yeah, valid point, we should document this as well (and maybe even provide one command to copy it from the CD to the harddisk, if this is available). Need to check it out.
