Well, I can assure you that you're not alone :) I'm dedicating much of my left-over time to work on gvinum, and you can see some of what I've been working on in the last status report. Some of this will hopefully come into CURRENT soon as Greg Lehey have had the time too review some patches. I'm almost done with the concat command too, but everytime I'm working on gvinum i bump into many things that could have been done better in terms of abstraction. More on this can be found here: http://lists.freebsd.org/pipermail/freebsd-arch/2006-August/005592.html As mentioned later in that post, a new type of volume manager should be designed to replace gvinum in the future. But it's still important to improve gvinum because of that fact that many still uses it. -- Ulf Lilleengen
