To add to this, I'd also be inclined to see this done in the larger context of writing at least a simplistic volume manager to contain arbitrary filesystems, then extending UFS to support the concept of dynamic resizing. That way you could extend (the most common request) a ufs partition much more flexibly across multiple partitions or disks, that being what people are *really* asking for when they cry for a resizable UFS. :-) - Jordan To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
