<modulesummary>Boot server for other Erlang machines.</modulesummary>
<description>
<p>This server is used to assist diskless Erlang nodes that fetch
all Erlang code from another machine.</p>
<p>This server is used to fetch all code, including the start
script, if an Erlang runtime system is started with
command-line flag <c>-loader inet</c>. All hosts specified
with command-line flag <c>-hosts Host</c> must have one
instance of this server running.</p>
<p>This server can be started with the Kernel configuration
parameter <c>start_boot_server</c>.</p>
<p>The <c>erl_boot_server</c> can read regular files and
files in archives. See <seealso marker="code"><c>code(3)</c></seealso>
and
<seealso marker="erts:erl_prim_loader"><c>erl_prim_loader(3)</c></seealso>
in ERTS.</p>
<warning><p>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.</p></warning>
