After asking the name and directory of the NFS server, the installation
procedure asks you about specific mount options you want to use, and it
says that if you are getting that "weak authentication" error from
Sun machines, you may want to use "-o respvc" or something like that
(look at the message displayed by the install procedure, I don't recall
exactly the option).
