On: Logging can be tricky

[jacques_chester]

Just to make sure we're talking about the same thing, a journalling FS isn't the same thing as a log-structured FS.

The first has a write-ahead log, the latter is basically just a log. So immediately writing to disk is relatively simple.

Yes. I haven't done anything with a log-structured FS. I have only played around with conventional filesystems.
