Oh, your tunables just reduce the number of inodes? That may come as a suprise to people that are using the larger disks to store images and web/ftp stuff. I guess we ought to leave it alone, maybe if I have the time I'll see about popping up a dialog to ask if they'd like to make the inode/fsck tradeoff. But since Kirk is getting close with his snapshot work it might really not be necessary. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] "I have the heart of a child; I keep it in a jar on my desk."
