Password-protect R script files
...OS based folder protection route, however making available such a method in the open forum would only kill the very spirit of R. But if someone is able to convince me the genuineness of his reasons to achieve such a purpose, I might decide to provide selective service to achieve the same.

Journal file location
...file system, I'd like to use an inode at a different cylinder group and some other set of blocks. Even if I'm allowed only to use one of the reserved inodes, is it possible to put the journal file somewhere in the "middle" of the file system rather than at the beginning ? Thanks, Vijayan

fsync in ext3: A question
...t file is in 'data=journal' mode, would the fsync() return once the data gets safely into the journal ? On the other hand, if that file is in 'data=writeback' mode, would the fsync() return only when the data gets safely into its actual location ? Any help is appreciated. Thanks, Vijayan

Transaction semantics in ext3
Hi, I have a doubt on how the transaction semantics work in ext3. When I copy a file, does the entire copy is treated as one transaction so that finally I have either the full file or no file. Or will it be split into multiple transactions which can result in copying partial files. thanks, Vijayan
