Due to history I won't go into, all my production (currently 7.2-RELEASE) systems are installed onto "dangerously dedicated" disks. What exactly do I need to do to upgrade them to 8.0? (I'm not asking for an upgrade procedure, I'm familiar with that, but rather, how this change impacts the upgrade.) I think that the suggestion that the disks need to be reformatted is extreme and I hope something less extreme will suffice. Also, just to be clear, does this statement refer to boot disks, data disks, or both? It doesn't make sense to me that "dangerously dedicated" could have an impact on UFS filesystems specifically. A partition table is just a partition table, regardless of what filesystems might be written on disks, yes? Am I misunderstanding something here? Thanks for helping to clear up my confusion... plw
