The temporary workaround during the transition period is to have two mount points for the file system. One gives you the new view of the data (attributes and all), while the other one just gives you the old unattributed one (suitable for tar'ing up C source code for distribution). > Actually, if kernel stat() isElement O(1) and > readdir() isElement O(n) [...] As part of indexing, I'm hoping for sorted directories (or with Reiser V4, that's a custom directory type plus plug-in). Then readdir() is O(log n) to find the place it left off from reading before, and so is stat() to find the file it is stat'ing. That reminds me about back links. Currently a file just has the count of the number of links to it, but doesn't know what they are (and people shouldn't be using this as the count of the number of items in a directory!). I'm experimenting with including a list of backlinks in my RAM disk file system for BeOS, and it comes in useful for an improved alias/hard link. Probably would also be useful for reconstructing directories (not a concern with RAM disks :-). - Alex
