Create file reltool.config:
{sys, [{erts, [{mod_cond, derived}, {app_file, strip}]},
{app_file, strip},
{rel, "test", "1", []},
{boot_rel, "test"},
{profile, embedded},
{incl_cond, exclude},
{app, kernel, [{incl_cond, include}]},
{app, stdlib, [{incl_cond, include}]},
{app, crypto, [{incl_cond, include}]}
]}.
Create an Erlang release named ‘test’ from ‘reltool.conig’ above:
BASH> erl -eval '{ok, [Config]} = file:consult("reltool.config"),{ok, Spec} = reltool:get_target_spec([Config]), _ = file:make_dir("test"), reltool:eval_target_spec(Spec, code:root_dir(), "test").' -s init stop -noshell
Now bring up the node and crash it:
BASH> export BINDIR=$(pwd)/test/erts-6.0.1/bin && $BINDIR/erlexec -boot test/releases/1/test -mode embedded
Erlang/OTP 17 [erts-6.0.1] [source-57e57ad] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

1> init:restart().
ok
2> {"init terminating in do_boot",{'cannot load',crypto,get_files}}

Problematic code in init.erl
load_mod_code(Mod, BinCode, FullName) ->
case erlang:module_loaded(Mod) of
false ->
case erlang:load_module(Mod, BinCode) of
{module,Mod} -> {ok,FullName};
{error,on_load} ->
?ON_LOAD_HANDLER ! {loaded,Mod},
{ok,FullName};
Other ->
exit({'cannot load',Mod,Other})
end;
_ -> % Already loaded.
{ok,FullName}
end.
?ON_LOAD_HANDLER ! {loaded,Mod}, crashed with ‘badarg’ because ?ON_LOAD_HANDLER was not alive
?ON_LOAD_HANDLER is not started for init:restart, bug ?
If boot the node with -init_dbug flag, below log can be observed, but not during init:restart
{running_on_load_handler,crypto}
{on_load_handler_returned_ok,crypto}
In fact, if any of the -on_load(…) modules gets loaded when booting, init:restart won’t work!
