Short-Description: Kernel NFS server support

Description: NFS is a popular protocol for file sharing across

TCP/IP networks. This service provides NFS server

functionality, which is configured via the

/etc/exports file.

END INIT INFO

Startup script for nfs-utils

The environment variable NFS_SERVERS may be set in /etc/default/nfsd

Other control variables may be overridden here too

test -r /etc/default/nfsd && . /etc/default/nfsd

Location of executables:

test -x "$NFS_MOUNTD" || NFS_MOUNTD=/usr/sbin/mountd test -x "$NFS_NFSD" || NFS_NFSD=/usr/sbin/nfsd test -x "$NFS_STATD" || NFS_STATD=/usr/sbin/statd

The user mode program must also exist (it just starts the kernel

threads using the kernel module code).

test -x "$NFS_MOUNTD" || exit 0 test -x "$NFS_NFSD" || exit 0

Default is 8 threads, value is settable between 1 and the truely

ridiculous 99

test "$NFS_SERVERS" -gt 0 && test "$NFS_SERVERS" -lt 100 || NFS_SERVERS=8

The default state directory is /var/lib/nfs

test -n "$NFS_STATEDIR" || NFS_STATEDIR=/var/lib/nfs

supported options:

stop

reload: reloads the exports file

restart: stops and starts mountd
