exports.8 refers to exports.5, which does not exist
Looked on stock Intel and Sparc installs and /usr/man/man5/exports.5
exists. 'man exports' shows exports.5. Shrug?
knfsd was not upgraded because of change in version numbering
scheme from betas to 6.0, which was why I didn't have the man
page on my 6.0 machine. mea culpa
