you seem to be making a general claim about all storage management solutions that i don't think can be backed up. as an example i have no rooting interest in, way back in 1996, i was able to use aix lvm to migrate a couple of hundred filesystems in many tens of vgs to tens of filesystems on a handful of vgs with mirrored lvs. i didn't find it hard at all to reallocate or resize anything. there were no partitions in sight. (i sure don't miss dasd.) > A venti-based system (which maybe presents an block device via > venti) can make runtime configuration much easier. combining functionality that is logically distinct is generally called unmodular, and a layering violation in this particular senerio. - erik
