Please confirm that you added a debug printout to
halt_reboot_pwoff and it is not triggering when halt
sends SIGUSR1 to init.
In this case, can you do this change int init.c:
static pid_t run(const struct init_action *a)
{
...
if (pid)
+{
+ bb_signals(0
+ + (1 << SIGUSR1) /* halt */
+ + (1 << SIGUSR2) /* poweroff */
+ + (1 << SIGTERM) /* reboot */
+ , halt_reboot_pwoff);
return pid;
+}
Basically, it restores SIGUSR1 handling in the parent
after child sets it to SIG_DFL.
Does this fix things?
