Summary: Improvement: Add more configuration options to
nfsserver init script & YaST

Situation:
We are running a high-availability NFS server with Kerberos support in a two
node cluster. The two nodes use a shared hostname to provide the NFS service to
the clients.
Problem:
In order to run NFS with Kerberos support on a shared hostname (which is not
the ACTUAL hostname of any machine), the init script of the NFS server
(/etc/init.d/nfsserver) of the NFS client (/etc/init.d/nfs) need to be patched.
In case there would be any update to the NFS server or client, these changes
will be overwritten.
Solution:
Add configuration options to /etc/sysconfig/nfs that will be passed on to the
NFS server and client init scripts.
More details:
I adding the following options in /etc/init.d/nfsserver:
---------
1) Make the location of the rpc_pipefs directory configurable (because we link
/var/lib/nfs to a DRBD device, thus the standard path /var/lib/nfs/rpc_pipefs
is not available on the DRBD slave, which causes the nfs client to malfunction)
2) Add shared hostname as an option to SVCGSSD
3) Add shared hostname as an option to NFSD

--------
I would like to variables $RPC_PIPEFS_DIR, $SVCGSSD_OPTIONS and $NFSD_OPTIONS
to be added to /etc/sysconfig/nfs such that their values are kept even with an
update of the nfskernel server.
For statd and sm_notify there exist the corresponding options variables
$STATD_OPTIONS and $SM_NOTIFY_OPTIONS already, which are configurable via YaST!
The addition of the $RPC_PIPEFS_DIR variable also is included in the init
script of the nfs client:

--------
Also, porting these changes to SLES11SP1 (or SP2) would be great, as we are
actually using an HA-NFS server with SLES11.1.
Reproducible: Always
