I second that, i love to see some background info! But it looks like either the release notes or the ext4 documenation needs updating:
=== Release notes === `ext4` does not guarantee atomic renames of new files over existing files in the event of a power failure shortly after the rename === ext4 docs ( http://www.mjmwired.net/kernel/Documentation/filesystems/ext4.txt#338 ) === the data blocks of the new file are forced to disk before the rename() operation is committed. This provides roughly the same level of guarantees as ext3, and avoids the "zero-length" problem that can happen when a system crashes before the delayed allocation blocks are forced to disk. -- [regression] dpkg fsync cause massive regression in Ubuntu Server and Alternate installation times https://bugs.launchpad.net/bugs/570805 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
