| 11 | Choose Y here if you want to allow other computers to access | |
| 12 | files residing on this system using Sun's Network File System | |
| 13 | protocol. To compile the NFS server support as a module, | |
| 14 | choose M here: the module will be called nfsd. | |
| 15 | ||
| 16 | You may choose to use a user-space NFS server instead, in which | |
| 17 | case you can choose N here. | |
| 18 | ||
| 19 | To export local file systems using NFS, you also need to install | |
| 20 | user space programs which can be found in the Linux nfs-utils | |
| 21 | package, available from http://linux-nfs.org/. More detail about | |
| 22 | the Linux NFS server implementation is available via the | |
| 23 | exports(5) man page. | |
| 24 | ||
| 25 | Below you can choose which versions of the NFS protocol are | |
| 26 | available to clients mounting the NFS server on this system. | |
| 27 | Support for NFS version 2 (RFC 1094) is always available when | |
| 28 | CONFIG_NFSD is selected. | |

| 49 | help | |
| 50 | Solaris NFS servers support an auxiliary NFSv3 ACL protocol that | |
| 51 | never became an official part of the NFS version 3 protocol. | |
| 52 | This protocol extension allows applications on NFS clients to | |
| 53 | manipulate POSIX Access Control Lists on files residing on NFS | |
| 54 | servers. NFS servers enforce POSIX ACLs on local files whether | |
| 55 | this protocol is available or not. | |
| 56 | ||
| 57 | This option enables support in your system's NFS server for the | |
| 58 | NFSv3 ACL protocol extension allowing NFS clients to manipulate | |
| 59 | POSIX ACLs on files exported by your system's NFS server. NFS | |
| 60 | clients which support the Solaris NFSv3 ACL protocol can then | |
| 61 | access and modify ACLs on your NFS server. | |
| 62 | ||
| 63 | To store ACLs on your NFS server, you also need to enable ACL- | |
| 64 | related CONFIG options for your local file systems of choice. | |
