Ok, here's another question to noone in particular:

    The EFS(Extended File System???) or "Clustering file system" seems,
by description, to be an extension of the standard "Fast File System"
FFS or UFS. Will the clustering file system be able to access old style
UFS partitions, or will newfs'ing be required?
