This branch of a2server only supports jessie and above, either Raspbian or Debian. While I was at it, I simplified the tests for what is and is not a supported OS. If there are bad kernels or firmwares we need to work around those should be fixes. This also means giving the user an option to interrupt the installation if they are trying to install on a Debian(ish) system that is too old or (more likely) too new. At least ivan.sh is now using a2cloud's system_ident script.
A2SERVER
AppleTalk server for Apple // computers developed by Ivan Drucker
Documentation here is sparse for the moment; see Ivan's site for information about A2SERVER and how it all works. There's a lot there and it's kind of evolved organically over the years just as the scripts themselves have, so it's going to be awhile before that information can be backfilled and perhaps organized into something you might call a user manual.
Such a manual should not be considered a replacement for Ivan's organic online documentation--those contents themselves represent Apple // history, if a relatively modern piece of it. As such they should be preserved as they are.
Developer note
This section used to describe how to run these scripts directly. That's changing. Watch this space.
