I have a friend's quad PPro box temporarily sitting in my garage that I've been using to play with 4.0-CURRENT and vinum. Since the last series of bug-fixes a few weeks ago, everything works as advertised. Just for my own curiosity, I've been running some simple (probably questionable) tests involving find|cpio of the source tree and then buildworld -j16 on various vinum volumes. So I thought I'd forward the results to current, for what it's worth. The biggest (non)surprise is how big a difference softupdates makes.
