+ help
+ The NFSv4 server needs to store a small amount of information on
+ stable storage in order to handle state recovery after reboot. Most
+ modern deployments upcall to a userland daemon for this (nfsdcld),
+ but older NFS servers may store information directly in a
+ recoverydir, or spawn a process directly using a usermodehelper
+ upcall.
+
+ These legacy client tracking methods have proven to be probelmatic
+ and will be removed in the future. Say Y here if you need support
+ for them in the interim.
