freebsd stable - May 2009 - devd doesn't fire event on boot

Hello,

Running 7.2-STABLE/amd64. I have a USB-disk and added stuff to devd to  
mount it readonly on attach. This does work if I attach it after booting  
up, but not if it is attached before booting.

[root@sjakie ~]# cat /etc/devd/philips.conf
attach 10 {
         device-name "umass[0-9]+";
         match "vendor" "0x0471";
         match "product" "0x083a";
         match "sernum" "20521126";
         action "/root/bin/mountphilips.sh";
};

[root@sjakie ~]# cat /root/bin/mountphilips.sh
#! /bin/sh
(
# Sleep, so geom and other kernel stuff can handle the disk
# before we try to mount it.
sleep 10
mount -v /mnt/backupdisk
) &

[root@sjakie ~]# grep backupdisk /etc/fstab
/dev/ufs/Extern /mnt/backupdisk ufs     ro,noauto       0       0

What can be wrong? Is it possible devd misses events which happened before  
devd was started?
Is this known behaviour?

Ronald.

devd throws away all events that happen prior to devd starting up I think.

The property sernum is not very reliable. Sometimes devd knows about it  
and sometimes not.
I removed the match on it and know it works.
