(It might even be maildir, but I think not). This is what has led to my very slow directory traversal times on backup. Cyrus does not offer a choice of formats in the sense of switching to something like mbox, and it is intended to be for large scale use. Functionally, it is a mail database. I suspect many other systems, even those offering a choice of format, won't let you mix different formats. So if you like maildir for some stuff, you may need to use it for all. So it seems to me it would be useful if the filesystem supported such useage patterns well.
