Is the larger size universally compatibile with NFS implementations? When
I tried to "Up" the read and write sizes to an old Unix box(IBM RT PC
running AOS, a VERY vanilla BSD 4.3 port), I would get I/O errors while
trying to write to an NFS volume mounted from the RT. This could very
well be some oddity of AOS, however(It's NFS is pretty ancient...).
