I've been setting "-o nfsvers=<vers>" systematically ever since nfsv4 |
| 30 |
was released... :( |

You can use "/etc/nfsmount.conf" to control the behavior of mount.nfs{,4}. |
| 33 |
|

Do you have "net-fs/nfs-utils nfsv41" in package.use? In the eix |
| 35 |
output below, nfs-utils is compiled with "-nfsv41" by default: |
| 36 |

Should mount.nfs4 try an nfs4.1 mount if nfs-utils is compiled with |
| 49 |
"-nfsv41"? Or is the use flag intended for rpc.nfsd only? |
