ZVOL/ZFS hosting UFS filesystems ... ERROR!

Hi all,

I need to use UFS within a ZVOL so that I can use POSIX ACLs.
i.e. since ZFS on FreeBSD doesn't (yet) support POSIX ACLs.

The problem
-~-~-~-~-~-

/boot/kernel/zfs.ko seems to be loaded after /etc/fstab is read. And I need zfs.ko to be
loaded before /etc/fstab is read i.e because to mount a ZVOL automatically
defined in fstab(5) zfs.ko needs to be loaded.

Currently when boostrapping I get the following error:

  "Can't stat /dev/zvol/data_dg/export/ufs
   Unknown error; help!
   ERROR: ABORTING BOOT (sending SIGTERM to parent)!"

And I drop into single user mode.

The line causing this in fstab(5) is:

   /dev/zvol/data_dg/export/ufs /export/mod ufs   rw,acls  1  1

Can anyone recommend how I can get around this ?

Thanks
