	Finally, is there a way to shut down the system
	gracefully and reboot from the commandline?

If you're booted from a file server, type
^P at a cpu server console, or echo reboot >/dev/reboot.
If not, you need to halt the disks first:
If you're standing at the machine, type
disk/kfscmd halt and then reset the machine.
If you want to do everything remotely,
I believe the following will suffice (I haven't
tried it recently, but it worked four years ago).

Russ

#include <u.h>
#include <libc.h>

void
main(void)
{
	int fd;
	Waitmsg w;

	fd = open("/dev/reboot", OWRITE);
	if(fd < 0)
		sysfatal("open: %r");

	switch(fork()) {
	case -1:
		sysfatal("fork: %r");
	case 0:
		execl("/bin/disk/kfscmd", "disk/kfscmd", "halt", nil);
		break;
	default:
		wait(&w);
		break;
	}

	fprint(fd, "reboot");
}

The chief of IDsoftware, the creator of Wolfenstein, Doom and Quake series.
He's been known to be a genius in his field (graphics), at least among
gamers...

Greetings, Plan 9ers.

I'm wondering: what's the lieterature base for Plan 9 like? are there
any really good books out there yet?
(O'Reilly & Assoc. "Plan 9 in a Nutshell"?)

John Carmack called Plan 9 "achingly beautiful". I tend to agree; in
spite of it's almost harsh austerity in certain places, there is so much
about it that is just "Right" as to make it irresistable. Who the hell
is John Carmack anyway? His name sounds very familiar.

Finally, is there a way to shut down the system gracefully and reboot
from the commandline?

(Hadda sneak that last one in on ya).


Good Day!
James
