May be a trick if your script build_key use the variable KEY_CONFIG:
Before to launch the script build_key, just add 2 lines:
Code:
KEY_CONFIG="/etc/openvpn/easy-rsa/openssl-1.0.0.cnf -batch"
export KEY_CONFIG

This trick set -batch option to openssl commande that use this variable without to modify build_key script.

Regards.

another idea that depends on how the build-key script invokes the openssl command.
If it is invoked via the PATH, just in this case create a script called "openssl" that will invoke the real openssl with an additional parameter (-batch) for example.
In your script:
Code:
PATH=path_of_your_script_openssl:$PATH
build-key "$username"
PATH=${PATH#*:}

And script openssl might look like:
Code:
#!/bin/bash
PATH=${PATH#*:}
openssl $@ -batch
exit $?

Regards.

BTRACEBACK(1)					     Network backup, recovery and verification					     BTRACEBACK(1)

NAME

	btraceback - wrapper script around gdb and bsmtp

SYNOPSIS

       btraceback /path/to/binary pid

DESCRIPTION

       btraceback is a wrapper shell script around the gdb debugger (or dbx on Solaris systems) and bsmtp, provided for debugging purposes.

USAGE

       btraceback  is called by the exception handlers of the Bacula daemons during a crash.  It can also be called interactively to view the cur-
       rent state of the threads belonging to a process, but this is not recommended unless you are trying to debug a problem (see below).

NOTES

       In order to work properly, debugging symbols must be available to the debugger on the system, and gdb, or dbx (on Solaris systems) must	be
       available in the $PATH.

       If  the	Director  or Storage daemon runs under a non-root uid, you will probably need to be modify the btraceback script to elevate privi-
       leges for the call to gdb/dbx, to ensure it has the proper permissions to debug when called by the daemon.

       Although Bacula's use of btraceback within its exception handlers is always safe, manual or interactive use of btraceback is subject to the
       same  risks  than  live debugging of any program, which means it could cause Bacula to crash under rare and abnormal circumstances.  Conse-
       quently we do not recommend manual use of btraceback in production environments unless it is required for debugging a problem.

ENVIRONMENT

       btracback relies on $PATH to find the debugger.

FILES

       /usr/lib/bacula/btraceback
	      The script itself.

       /usr/sbin/btraceback
	      symbolic link to /usr/lib/bacula/btraceback

       /etc/bacula/scripts/btraceback.gdb
	      the GDB command batch used to output a stack trace
