Sort ordering
...ey1, relevance, key2. Unless I spool out the entire result set or write some C++. I wonder if we need a new 'sort by' function that accepts any combination of keys and relevance in any order?

The goal is to be able to view snapshots stored on the media and merge these into the list of viewable snapshots in nautilus giving the user a broader selection of restore points. In an ideal world we would like to detect the insertion of the

rename(2), atomicity, crashes and fsync()
Hi all, Recently there''s been discussion [1] in the Linux community about how filesystems should deal with rename(2), particularly in the case of a crash. ext4 was found to truncate files after a crash, that had been written with open("foo.tmp"), write(), close() and then rename("foo.tmp", "foo").
