The st_gen field > is a 4 byte value which is different for each item on the filesystem. I've worked on other systems in the past where we only returned st_gen if the caller was root. If I remember right, the last time I looked at how the kernel assigned generation number, it didn't do a very good job of it (they were pretty predictable). We should probaby change them to use the random() kernel function. -- Mike Pritchard mpp@FreeBSD.org "Go that way. Really fast. If something gets in your way, turn"
