The @code{(gnu services nfs)} module provides the following services,
|

which are most commonly used in relation to mounting or exporting
|

directory trees as @dfn{network file systems} (NFS).

@subsubheading RPC Bind Service
|
||||
@cindex rpcbind
|

|

The @code{(gnu services nfs)} module provides the following:
|
||||
The RPC Bind service provides a facility to map program numbers into
|
||||
universal addresses.
|
||||
Many NFS related services use this facility. Hence it is automatically
|
||||
started when a dependent service starts.

@subsubheading Pipefs Pseudo File System
|

@cindex pipefs

@cindex rpc_pipefs
|

The pipefs file system is used to transfer NFS related data

between the kernel and user space programs.

|

@table @asis
|

@item @code{mount-point} (default: @code{"/var/lib/nfs/rpc_pipefs"})

@cindex GSSD
|

@cindex GSS
|

@cindex global security system
|
||||
|
||||
The @dfn{global security system} (GSS) daemon provides strong security for RPC
|
||||
based protocols.
|
||||
Before exchanging RPC requests an RPC client must establish a security
|
||||
context. Typically this is done using the Kerberos command @command{kinit}
|
||||
or automatically at login time using PAM services.

@subsubheading IDMAP Daemon Service
|

@cindex idmapd
|

@cindex name mapper
|
||||
|
||||
The idmap daemon service provides mapping between user IDs and user names.
|
||||
Typically it is required in order to access file systems mounted via NFSv4.
|
||||
|
||||
@defvr {Scheme Variable} idmap-service-type

@end defvr

Data type representing the configuration of the IDMAP daemon service.

This type has the following parameters:
|
||||
@table @asis
|
||||
@item @code{nfs-utils} (default: @code{nfs-utils})
|
||||
The package in which the @command{rpc.idmapd} command is to be found.
|

|

@item @code{pipefs-directory} (default: @code{"/var/lib/nfs/rpc_pipefs"})
|

The directory where the pipefs file system is mounted.

@item @code{domain} (default: @code{#f})
|

The local NFSv4 domain name.
|

This must be a string or @code{#f}.
|
||||
If it is @code{#f} then the daemon will use the host's fully qualified domain name.
