nfsmount.conf - Configuration file for NFS mounts
Configuration file for NFS mounts that allows options to be set globally, per server or per mount point.
The configuration file is made up of multiple section headers followed by variable assignments associated with that section. A section header is defined by a string enclosed by [ and ] brackets. Variable assignments are assignment statements that assign values to particular variables using the = operator, as in Proto=Tcp. The variables that can be assigned are the set of NFS specific mount options listed in nfs(5) together with the filesystem-independant mount options listed in mount(8) and three additions: Sloppy=True has the same effect as the -s option to mount, and Foreground=True and Background=True have the same effect as bg and fg.
Options in the config file may be given in upper, lower, or mixed case and will be shifted to lower case before being passed to the filesystem.
Boolean mount options which do not need an equals sign must be given as "option=True". Instead of preceeding such an option with "no" its negation must be given as "option=False".
Sections are broken up into three basic categories: Global options, Server options and Mount Point options.
[ NFSMount_Global_Options ] - This statically named section defines all of the global mount options that can be applied to every NFS mount.
[ Server "Server_Name" ] - This section defines all the mount options that should be used on mounts to a particular NFS server. The "Server_Name" strings needs to be surrounded by '"' and be an exact match (ignoring case) of the server name used in the mount command.
[ MountPoint "Mount_Point" ] - This section defines all the mount options that should be used on a particular mount point. The "Mount_Point" string needs to be surrounded by '"' and be an exact match of the mount point used in the mount command. Though path names are usually case-sensitive, the Mount_Point name is matched insensitive to case.
The sections are processed in the reverse of the order listed above, and any options already seen, either in a previous section or on the command line, will be ignored when seen again.
These are some example lines of how sections and variables are defined in the configuration file.
[ NFSMount_Global_Options ]
The TCP/IPv4 protocol will be used on every NFS mount.
[ Server "nfsserver.foo.com" ]
A 32k (32768 bytes) block size will be used as the read and write size on all mounts to the 'nfsserver.foo.com' server. UDP/IPv6 is the protocol to be used.
[ MountPoint "/export/home" ]
All mounts to the '/export/home' export will be performed in the background (i.e. done asynchronously).
- Default NFS mount configuration file
- When this directory exists and files ending with ".conf" exist, those files will be used to set configuration variables. These files will override variables set in /etc/nfsmount.conf
