You need to create a name space directory and
set $NAMESPACE.  Since the machines I use are all
single-user, I typically just use the machine name:

	h=`{hostname}
	NAMESPACE=/tmp/ns.$h
	mkdir -p $NAMESPACE

See intro(4) for information about name space directories.

make sure the permissions on the directory are 700.
it won't work without that.

not true.  all mine are mode 755 (i've never even looked before)
and it works for me.

interesting, lib9/getns.c has this code:

; grep -C 5 0777 $home/cvs/plan9/src/lib9/getns.c
	if((d->mode&0777) != 0700 || strcmp(d->uid, getuser()) != 0){
		werrstr("bad name space dir %s", p);
		free(p);
		free(d);
		return nil;
	}
	free(d);
	return p;
}

i forgot about this. this check is only executed if $NAMESPACE
is not set. (that is, when deriving the namespace from $DISPLAY.)

Permission is 1777 for /tmp on both FreeBSD 6 and 5.

for any sane configuration, /tmp != $NAMESPACE.

Oh, I misunderstood what you told me the first time. I was thinking "the
directory _where_ the namespace will be created". That is really not what
you said to me.

Finaly, my $NAMESPACE is really 700 and it works.
