Steve, I have some charts from a couple of larger presentations that give an overview of spool and how to spool your consoles. It's not specific to Linux and doesn't go deep into the internals, but it should give you the general picture.I'll gather the charts into a single file and send them to you offline (it will come from [EMAIL PROTECTED] ).
I have a older presentation "somewhere" that digs deeper into the internals, but I'll have to dig around for it. John Franciscovich z/VM Development
