 Nfsserver helps to manage the Linux nfs server as a failover-able resource in Linux-HA.
 It depends on Linux specific NFS implementation details, so is considered not portable to other platforms yet.

 <parameter name="nfs_init_script" unique="0" required="0">
 <longdesc lang="en">
 The default init script shipped with the Linux distro.
 The nfsserver resource agent offloads the start/stop/monitor 
 work to the init script because the procedure to start/stop/monitor 
 nfsserver varies on different Linux distro. In the event that this
 option is not set, this agent will attempt to use an init script at 
 this location, ${DEFAULT_INIT_SCRIPT}, or detect a systemd unit-file 
 to use in the event that no init script is detected.

 The tool to send out NSM reboot notification; it should be either sm-notify or rpc.statd.
