In 1.4.7 it was 2tb. In 1.4.8 it will be another 32 powers of 2
larger, a number I am too lazy to calculate.

Possibly. Note that in Solaris 10 if you update too far you will
eventually take a UFS change which breaks the OpenAFS inode
fileserver, and by default Solaris 10 builds starting in 1.4.8 will
give you a namei fileserver for that reason. For performance reasons
you probably want ZFS-backed namei partitions, especially if you are
setting up large partitions.
