Module
erl_boot_server
Module Summary
Boot server for other Erlang machines.
Description
This server is used to assist diskless Erlang nodes that fetch all Erlang code from another machine.
This server is used to fetch all code, including the start script, if an Erlang runtime system is started with command-line flag -loader inet. All hosts specified with command-line flag -hosts Host must have one instance of this server running.
This server can be started with the Kernel configuration parameter start_boot_server.
The erl_boot_server can read regular files and files in archives. See code(3) and erl_prim_loader(3) in ERTS.
The support for loading code from archive files is experimental. It is released before it is ready to obtain early feedback. The file format, semantics, interfaces, and so on, can be changed in a future release.
