Well, as far as I understood it (that is, not so far :-p), reiser4
seemed to have a stronger and more efficient journal than ext3. That
is not what everyone believes, but reiser4 was to be designed that way
more or less... But I guess that ext3 and its very-heavily-tested
journal can still be more trusted than any newcomer.

Truth is, I would have been glad to play with reiser4 on a large
amount of data, just because I was interrested on the theories behind
it (including the database-filesystem strange wedding Hans tried to
organize). Maybe it's too great a risk for a production system.

Well, anyway, thanks for the advice. Guess I'll have to stay on ext3
if I don't want to have nightmares...
