How so? The flag is in the partition table. What data is written to the partition has nothing to do with the flag. Whether you have a filesystem or not, the flag is still there in the partition table. > Nothing goofy. Just the property of the lvm/raid. Because when to > make a partition to lvm/raid, the filesystem will be ripped out. Not by parted it won't. We just update the partition table, and it is up to the user to mess with the filesystem. If they don't run pvcreate on the partition after setting the lvm flag, then the filesystem is still there and works just fine. These flags simply don't matter in practice, and so I never bother setting them even though I do use raid and lvm.
