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

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