yeah, but not much more use. So I downloaded the source, and see that in
halt.c the halt/poweroff command creates them. do_shutdown just calles
shutdown.
if (c != '0' && c != '6') {
char *file;
if (do_poweroff) {
file = strdup("/poweroff");
} else {
file = strdup("/halt");
}
close(open(file, O_CREAT|O_RDWR, 0644));
free(file);
do_shutdown(do_reboot ? "-r" : "-h", tm);
}
So that answers that, but I have forgotten the orignal issue. How/when is
/etc/rc.d/init.d/halt called? We know that calling halt -p or poweroff
will do what we want, and calling shutdown will not (unless the /poweroff
file is created), but I don't recall how we got started with this one :)
My 6.2 box has a /usr/bin/shutdown script that seems to make all thsi work
ok - maybe this is the critical difference, as on my 7.0 box
/sbin/shutdown gets called directly instead.
