nfs-utils/nfsserver.init
Neil Brown ce3ce09113 - nfsserver.init / sysconfig.nfs: allow NFSv3 service 
to be disabled so only NFSv4 can be used. bnc#598671
- nfs-v2-disable.patch: mountd support for above
- nfs.init: unmount bind mounts with '-l' to ensure they
     really unmount. bnc#598681

# Short-Description: Start the kernel based NFS daemon
### END INIT INFO
. /etc/sysconfig/nfs
# Shell functions sourced from /etc/rc.status:
# rc_check check and set local and overall rc status
# rc_status check and set local and overall rc status
# rc_status -v ditto but be verbose in local rc status
# rc_status -v -r ditto and clear the local rc status
# rc_failed set local and overall rc status to failed
# rc_failed <num> set local and overall rc status to <num><num>
# rc_reset clear local rc status (overall remains)
# rc_exit exit appropriate to overall rc status
. /etc/rc.status
# First reset status of this service
rc_reset
# Return values acc. to LSB for all commands but status:
# 0 - success
# 1 - generic or unspecified error
# 2 - invalid or excess argument(s)
# 3 - unimplemented feature (e.g. "reload")
# 4 - insufficient privilege
# 5 - program is not installed
# 6 - program is not configured
# 7 - program is not running
#
# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signalling is not supported) are
# considered a success.
