Net-Boot
v0.1.0
This is simple implementation of a Net-Boot solution.
It simply allows you to have multiple computers in a network, that request and get updates from a different computer that "serves" EEPROM Programs.
The Software Distribution occurs over network messages. Requiring all comptuers to have a Network Card an be connected with each other (this includes WAPs).
You can have multiple Net-Boot servers in the same network, serving different programs. Undefined behaviour may occur if you have multiple Servers providing the same program.
If you start a Server (or restart one), it will broadcast a restart command to all computers running one of the programs the Server is providing. Effectively causing a Software Update and Reboot.
The clients request a program upon start/after restart. They will retry indefinetly after some amount of time without response of a Server.
The loaded coded will be executed in a protected call, allowing for an automatic computer restart in the case of a error.

Warning
|
The Client will override the event.pull(…) function with a wrapper, that filters out Net-Boot messages.
The main use for this is the software update functionallity.

|
Tip
|
Additionally, the loaded Program can define a global netBootReset() function. Which will be called before the restart when the client receives an software update command, allowing the code to do some manual "cleanup" (again protected, causing a restart instead of a system crash).

You can define a matching custom communication port for both server and client.
EEPROMs
The network server, serving multiple EEPROM Programs to Net-Boot-Clients in the Network. This server does not use the FileSystem for program discovery.
The network client that requests and loads a EEPROM Program served by a Net-Boot-Server in the Network.
