I partition manually these days with 9.0-R because most servers are either using gmirror, which I want setup before the install, or a RAID card which means partitions need to be aligned to the stripe boundaries. So I just "newfs -U -L" and keep journaling off and wouldn't have realized there is at least some mitigation that will make it into 9.1-R. I still stand by my feeling that it should not be on by default though, because it breaks snapshots and by extension dump -L which I consider to be a pretty awesome feature of FreeBSD. If you have partitions with enabled it means booting up in single user to undo it which is a hassle for a server if it's in production (I realize that's a bit whiny :P). -- Adam Strohl http://www.ateamsystems.com/
