I'm waiting for evilfs: the filesystem that *always* writes the deletion of data to disk synchronously,
but *never* writes any new data (file data, directory data, anything) to a permanent location until
you've called fsync on the file's fd, the containing directory's fd, and the fd of every directory up the
tree to the root (or call sync, of course).
Hopefully it can be the default fs for Ubuntu Jaded Jackal. If anyone complains, I'm sure "But POSIX
says it's okay to do that, the apps are broken for not obsessively calling sync after every write!" will
satisfy everyone. :)
