> There are no options for loader.conf which speak to this as near as I can tell at least not based on that man page, guess I can just try random stuff like verbose_loading but… I think I already did and it wasn’t helpful. The only way I’ve been able to activate the option is at the boot prompt, hit 7 hit 6 backspace 1 which sucks, I’m trying to  write a driver and its a pain in the ass.

bootverbose is defined in `sys/kern/init_main.c`. You may want to have `options 	BOOTVERBOSE=1` in the kernel conf file to ease you development.

```
...
#ifndef BOOTVERBOSE
#define BOOTVERBOSE     0
#endif
int     bootverbose = BOOTVERBOSE;
SYSCTL_INT(_debug, OID_AUTO, bootverbose, CTLFLAG_RW, &bootverbose, 0,
        "Control the output of verbose kernel messages");
...
```

See also `sys/conf/NOTES` .
