Handbook obsolescence scan: "The vinum Volume Manager"

[Warren Block]

Next on the list of potentially outdated things in the Handbook: "The 
vinum Volume Manager", a whole chapter on vinum.  Actually, it is really 
now about gvinum.

Are there any situations where new users should be advised to use gvinum 
rather than ZFS or gconcat/gstripe/gmirror?

What reasons are there for this chapter to remain in the Handbook given 
the newer, simpler alternatives?

If the information should remain, why should it be separate from the 
GEOM chapter?
