Or maybe the top dirs of the remote filesystems.

So if you have 2 local partitions (disks) mounted it won't get to the 2nd. Use -prune with -fstype or the path to restrict. find / -path /net -prune -o -print find / -fstype nfs -prune -o -print

Now I'm trying to find where there are find commands in my cron jobs. I think the last bunch of them are in my rootkit checker.
