ufs2 on a vinum volume

[F. Even]

I am installing 5.1R on a P3-700 w/ 2 9GB SCSI drives.  I would like 
to use UFS2 along with all of the extended attributes, ACL's, etc.  If 
I use vinum on this system, will I still be able to use and take 
advantage of all of the features of UFS2?  I'm wondering, as part of 
the process of setting up vinum indicates I have to define partitions 
as type "vinum."  

Thanks,
Frank
