File 0004-Centralize-dependencies-on-the-auth-unit.patch of Package nfs-utils.3350

Subject: [PATCH] Centralize dependencies on the auth unit.

With this patch either gssproxy or rpc.svcgssd are started only if the
auth module is requested, and it finds a keytab.
If the wants are in the main nfs-client or nfs-server unit files then
the two deamons are started unconditionally and would require
conditions which we can test once and for all in a single unit file
instead.

Change also Before and After statments accordingly to properly
serialize loading modules and starting daemons in 3 steps
1. load kernel GSS auth module
2. start GSS handling daemons
3. start NFS client/server daemons
