Rebar ./bin/sp restart report {'cannot load',asn1rt_nif,get_files} and can not start - linux

Question

Environment
Mac OS X 10.10.5
Erlang/OTP: 17.5
rebar 2.6.0 17 20150818_094957 git 2.6.0-16-g3239e74-dirty
It is an example of application from the book Programming Erlang. I have git push to github
Steps to reproduce the error
build
$ git clone https://github.com/mingchaoyan/sellaprime.git
...
$ cd sellaprime
$ rebar prepare-deps
...
$ rebar compile
...
release
$ mkdir rel
$ cd rel
$ rebar create-node nodeid=sp
...
edit reltool.config as follow
```
%% -*- mode: erlang -*-
%% ex: ft=erlang
{sys, [
{lib_dirs, []},
{erts, [{mod_cond, derived}, {app_file, strip}]},
{app_file, strip},
{rel, "sp", "1.0.0",
[
kernel,
stdlib,
sasl,
goldrush,
lager,
sp
]},
{rel, "start_clean", "",
[
kernel,
stdlib
]},
{boot_rel, "sp"},
{profile, embedded},
{incl_cond, derived},
{excl_archive_filters, [".*"]}, %% Do not archive built libs
{excl_sys_filters, ["^bin/(?!start_clean.boot)",
"^erts.*/bin/(dialyzer|typer)",
"^erts.*/(doc|info|include|lib|man|src)"]},
{excl_app_filters, ["\.gitignore"]},
{app, goldrush, [{mod_cond, app}, {incl_cond, include}, {lib_dir, "../deps/goldrush"}]},
{app, lager, [{mod_cond, app}, {incl_cond, include}, {lib_dir, "../deps/lager"}]},
{app, sp, [{mod_cond, app}, {incl_cond, include}, {lib_dir, ".."}]}
]}.
{target_dir, "sp"}.
{overlay, [
{mkdir, "log/sasl"},
{copy, "files/erl", "\{\{erts_vsn\}\}/bin/erl"},
{copy, "files/nodetool", "releases/\{\{rel_vsn\}\}/nodetool"},
{copy, "sp/bin/start_clean.boot",
"\{\{erts_vsn\}\}/bin/start_clean.boot"},
{copy, "files/sp", "bin/sp"},
{copy, "files/sp.cmd", "bin/sp.cmd"},
{copy, "files/start_erl.cmd", "bin/start_erl.cmd"},
{copy, "files/sys.config", "releases/\{\{rel_vsn\}\}/sys.config"},
{copy, "files/vm.args", "releases/\{\{rel_vsn\}\}/vm.args"}
]}.
```
then
$ rebar generate
...
start
$ cd sp
$ ./bin/sp start
$ ./bin/sp getpid
...
$ ./bin/sp attach
start an another erlang shell
erl -name 'other#127.0.0.1' -noinput -noshell -eval "rpc:call('sp#127.0.0.1', init, restart, [])" -setcookie sp
then the first erlang shell will report
sp#127.0.0.1)1> {"init terminating in do_boot",{'cannot load',asn1rt_nif,get_files}}
How this happened?
And why asn1rt will be released, actually I didn't config it in reltool.config
Thank you!

You can find an answer in this old rebar issue: you need to prevent the boot script from loading the crypto module. To do this, edit the sp/bin/sp script and remove -mode embedded from the CMD variable setting, changing this:
CMD="$BINDIR/erlexec $SLIM_ARGS -boot $RUNNER_BASE_DIR/releases/$APP_VSN/$BOOTFILE -mode embedded -config $CONFIG_PATH -args_file $VMARGS_PATH"
to this:
CMD="$BINDIR/erlexec $SLIM_ARGS -boot $RUNNER_BASE_DIR/releases/$APP_VSN/$BOOTFILE -config $CONFIG_PATH -args_file $VMARGS_PATH"
