rc  libnfsidmap1
0.8-1                                An nfs idmapping library
ii  libnfsidmap2
0.20-1                               An nfs idmapping library
ii  nfs-common
1:1.1.2-6lenny2                      NFS support files common to client and
serve

hammerhead:/home/mark# ls /etc/init.d | grep nfs
mountkernfs.sh
mountnfs-bootclean.sh
mountnfs.sh
nfs-common
umountnfs.sh
hammerhead:/home/mark#
