UFS not 64-bit clean?

I'm fooling with using UFS, and I notice that I get in trouble at the 4-gig limit. Is the darwin UFS implementation not 64-bit clean? Thankfully, I don't have this trouble with NFS or HFS+, but I'm trying to have a FS that's 1) local 2) case sensitive 3) LFS-ready I'm not particularly interested in a discussion of why I want (2); let's try not to repeat all of that here :/ thanks ---- Chris J.
