Re-read what I wrote. To put it another way, "mkfs S1 + resize to > S2" does not produce precisely the same layout as "mkfs S2". And in what way is that important? I mean, really, if this is your argument that ext3 online resizing is a "hack" then it is pretty weak. This does not affect the operation or compatibility of the resized filesystem all the way back to the stone age (i.e. every single ext2 kernel ever will work with the resized filesystem). That is why online resizing (and the resize inode) are a COMPAT feature. If I "cp b a /mnt/newfs" and "cp a b /mnt/newfs" "a" and "b" will have different inode numbers too, but doesn't mean that "cp" is a "hack".
