Specially sized minidisks are not the only option. Think LVM. If you're trying to get free from the battle of wasted space versus wasted time and effort, logical volumes work really well. Nothing else in Linux land comes close. If you're running on VM, you can and should consider using the CP Directory to present specially sized minidisks. That is, VM becomes your logical volume manager. You have *options*. You have flexibility way beyond what CDL offers and without the funky special first track. If your shop is better served by giving Linux guests large chunks (or if you're doing LPAR where "large chunks" of DASD are the rule), feed said large chunks to LVM and let LVM slice and dice ... and season to taste. This is not easy to say because I know I'm stepping on a developer's toes.
