exec_init_fn now either returns NULL (success) or a string which indicates the error that occured during service engine initialization. If an error occurs, corosync will exit. This patch adds ykd and makes other suggestions from Fabio Di Nitto. Signed-off-by: Steven Dake <sdake@redhat.com> Reviewed-by: Fabio Di Nitto <fdinitto@redhat.com>
