Comment # 1 on bug 956558 from boo35 boo35

Note 2 rpc-*gssd.service files

    systemctl list-unit-files | grep gss
        auth-rpcgss-module.service              static  
        rpc-gssd.service                        static  
        rpc-svcgssd.service                     static  

both provided by CLIENT 'nfs-client' package,

    rpm -q --whatprovides /usr/lib/systemd/system/rpc-gssd.service
/usr/lib/systemd/system/rpc-svcgssd.service
        nfs-client-1.3.0-9.1.x86_64
        nfs-client-1.3.0-9.1.x86_64

but both (1) providing SERVER security svcs, and (2) looking very similar

    cat rpc-gssd.service 
        [Unit]
        Description=RPC security service for NFS client and server
        DefaultDependencies=no
        Conflicts=umount.target
        Requires=var-lib-nfs-rpc_pipefs.mount
        After=var-lib-nfs-rpc_pipefs.mount

        ConditionPathExists=/etc/krb5.keytab

        PartOf=nfs-utils.service

        Wants=nfs-config.service
        After=nfs-config.service

        [Service]
        EnvironmentFile=-/run/sysconfig/nfs-utils

        Type=forking
        ExecStart=/usr/sbin/rpc.gssd $GSSDARGS

    cat rpc-svcgssd.service 
        [Unit]
        Description=RPC security service for NFS server
        DefaultDependencies=no
        Requires=var-lib-nfs-rpc_pipefs.mount
        After=var-lib-nfs-rpc_pipefs.mount local-fs.target
        PartOf=nfs-server.service
        PartOf=nfs-utils.service

        After=gssproxy.service
        ConditionPathExists=|!/run/gssproxy.pid
        ConditionPathExists=|!/proc/net/rpc/use-gss-proxy
        ConditionPathExists=/etc/krb5.keytab

        Wants=nfs-config.service
        After=nfs-config.service

        [Service]
        EnvironmentFile=-/run/sysconfig/nfs-utils
        Type=forking
        ExecStart=/usr/sbin/rpc.svcgssd $SVCGSSDARGS

Why are there 2 similar services here?  Wondering if that's causal at boot.
