@kranu: It's the random. And it'll only slow the *cold* boot process down. (A little. With 500 files, I'd say something between 10 and 20s. A vanilla K3 cold boot is already slow as hell.) Good thing we pretty much never have to fully restart that thing

.
And a defrag makes no sense, it's a flash based storage (And you don't have direct access to the real underlying vfat FS anyway).
