It just works, for me.

No issues, really - had an unexpected benefit this afternoon - thunderstorms came through, and I'm not hitched to a UPS, so I switched off my workstation. When it seemed that the bulk of the boomers had passed, I switched it back on. 'Replayed' a few transactions, no problems (fast!). This might be a good thing for Linux-based consumer devices, I suppose (A/V players, etc.).

I've heard disk quotas aren't supported under reiserfs - is this still true? (I dunno, I don't use 'em).
