I can think of two ways of doing this:
1. Write a port driver in C (or another language) that would handle
SIGTERM events and dispatch them to the linked Erlang process using
message passing. (If interested I can provide you with such code,
though I believe the second approach is easier).
2. Call some function that dumps state from another node. Here is an
example of calling server:dump_state() on the 'nodename' node from
echo "rpc:call('nodename@`hostname -s`', server, dump_state, )." | \
erl -sname restarter -hidden
