Thanks for the link, describes indirect blocks in a nutshell. Does anyone else get confused by the unclear usage of the term "block"? Given that a *nix block is always 512 bytes (or is it?) and a disk block is a variety of sizes. Most documentation uses the generic term block without any effort to indicate which of the two they are talking about.
