And of course, we > need something more specific than the above. I have not been following current but I read any emails sent directly to me without a mailing list in the cc. I also was not aware of this. I had not heard of any filesystem corruption problems at all. If there are any, I also am not comfortable with enabling it by default. I want to fix that first. I have blocked off next week to work on this. I already sent an email out to current@ requesting bug reports. Please if you have anything else let me know immediately so I can prioritize it and start investigating. Thanks, Jeff > > Kirk McKusick >
