3 Open Issues

(24 May 2006) The NFSv4 client in 5.5-RELEASE is an unfinished prototype, and there are a number of issues with it (many documented in the FreeBSD GNATS database) that make it unusable in many situations. Given the state of 5-STABLE development, it is unlikely that these will be resolved on this development branch.
