I agree with the approach. But why write a simplistic volume manager when we already have vinum? > That way you could extend (the most common request) a ufs partition > much more flexibly across multiple partitions or disks, that being > what people are *really* asking for when they cry for a resizable > UFS. :-) Correct. That's why, as Julian observes, I'm collecting code. If somebody else wants to work on this, feel free to contact me. I don't see myself doing it in the very near future.
