A. Background
rpc.pcnfsd is a remote procedure call used by NFS clients which is
a service providing username and password authentication for system
which have NFS client software installed.

rebooting the system. The main patch requires a libc patch,
which in turn requires a kernal patch.

all the documented patch dependencies. The dependencies will be
