Patch Installation Instructions: 

  AS ROOT:
 
  After extracting patch contents into /tmp, become root and install
  the patch as follows:

  1) Save the original files as .FCS:
 
        mv /usr/etc/rpc.lockd /usr/etc/rpc.lockd.FCS
        mv /usr/etc/rpc.statd /usr/etc/rpc.statd.FCS
        mv /usr/kvm/sys/ufs/lockf.h /usr/kvm/sys/ufs/lockf.h.FCS
        mv /usr/include/ufs/lockf.h /usr/include/ufs/lockf.h.FCS
        mv /usr/kvm/sys/`arch -k`/OBJ/ufs_lockf.o /usr/kvm/sys/`arch -k`/OBJ/ufs_lockf.o.FCS
 
  2) Copy in the new patched files into the correct locations:

        cp /tmp/etc/rpc.lockd /usr/etc/rpc.lockd
        cp /tmp/etc/rpc.statd /usr/etc/rpc.statd
        cp /tmp/sys/ufs/lockf.h /usr/include/ufs
        cp /tmp/sys/ufs/lockf.h /usr/kvm/sys/ufs
        cp /tmp/sys/`arch -k`/ufs_lockf.o /usr/kvm/sys/`arch -k`/OBJ
 
  3) Set ownership and file mode permission on all newly installed files:

        chmod 755 /usr/etc/rpc.lockd /usr/etc/rpc.statd
        chown root.staff /usr/etc/rpc.lockd /usr/etc/rpc.statd

        chmod 444 /usr/include/ufs/lockf.h
        chown root.staff /usr/include/ufs/lockf.h

        chmod 444 /usr/kvm/sys/ufs/lockf.h
        chown root.staff /usr/kvm/sys/ufs/lockf.h
 
        chmod 444 /usr/kvm/sys/`arch -k`/OBJ/ufs_lockf.o
        chown root.staff /usr/kvm/sys/`arch -k`/OBJ/ufs_lockf.o

  4) Rebuild a new kernel and boot the machine using the new kernel:

	Rerun /etc/config <kernel-name> and make and install the new kernel.
 
	Please refer to the system and networking administration manual
	for details on building and installing a new kernel.
