tinderbox - tinderd and nullfs?

[Torfinn Ingolfsen]

Hello,

I have installed tinderbox[1] and is now trying to get tinderd to
work. I have read the information at the web page[2], but it is very
terse.
Note: I am using nullfs instead of nfs.
Even if I added " -nullfs" to tinderd_flags, tinderd just sits there
and doesn't want to start a build.
And there is a port in the queue:
root at kg-vm# ./tc listBuildPortsQueue
+=====+===========================+=======+==+
|  Id | Build Name                | Port Directory                      | Pri |
+=====+===========================+=======+===+
|   1 | 7.1-FreeBSD               | net-p2p/amule2                   |  10 |
+-----+---------------------------+-------------------------------------+-----+

But tinderd does nothing:
root at kg-vm# ps ax | grep tinder
51574  p0  S+     0:00.00 grep tinder
50765  p2  I      0:00.02 /bin/sh -T
/usr/local/tinderbox/scripts/tinderd -nullfs

What am I doing wrong?
