Thanks, Seth for this info. Definitely worth keeping in mind.

Hm. I think Reiser is for those "make sure you know what aou're doing".
I have myself some partitions on Reiser, but I'm not so sure I would
base critical stuff on it.

I'm too maxed-out at the moment to go trolling through the kernel change
logs to see whether anything might have changed in dir_index in the last
three years, but it might be interesting.

Thanks, regards
