installworld via NFS with FreeBSD 8

[thc]

Hello

I have a concern with the deployment of FreeBSD 8.1.
I usually compile on a server and deploy the result by NFS.
It works fine with FreeBSD 6 and 7, but curiously,
I just can not get the same result with FreeBSD 8.1 (or with 8.0).


Here is the df of the source:
Filesystem 1K-blocks Used Avail Capacity Mounted on
...
/dev/da0s1f 10,655,968 3,410,840 6,392,652 35% / exports
...
<above>:/export/src    12681998 5436870 6392652 46% /usr/src
<above>:/exports/obj   12681998 5436870 6392652 46% /usr/obj
<above>:/export/ports  12681998 5436870 6392652 46% /usr/ports

The partitions are mounted via rc.local via
/sbin/mount-t unionfs /export/src /usr/src

Here is my exports file:
/exports -alldirs -maproot=root -network 192.168.40.0 -mask 255.255.255.0

The file /etc/make.conf on both servers is empty.
Server and client are ntp synchronised.

Here is the excerpt from fstab on the client:
srcf8: /exports/obj /usr/obj nfs rw 0 0
srcf8: /export/src  /usr/src nfs rw 0 0

The client is first installed with the CD-ROM with minimal version.
I've tested a with an All install from CDROM, and got the same problem

I copied the file /usr/src/share/info/dir-tmpl missing on the client,
but it is not enough.

The command make ends installworld
make: do not know how to make audit_uevents.h. Stop

Does someone how to correct this trouble?
Thanks.
