compare this with yours:


,----[  head -n 14 /etc/init.d/nfs-common  ]---------------------------


#!/bin/bash

### BEGIN INIT INFO
# Provides:          nfs-common
# Required-Start:    $portmap $time
# Required-Stop:     $time
# Default-Start:     2 3 4 5 S
# Default-Stop:      0 1 6
# Short-Description: NFS support files common to client and server
# Description:       NFS is a popular protocol for file sharing across
#                    TCP/IP networks. This service provides various
#                    support functions for NFS mounts.
### END INIT INFO
`-----------------------------------------------------------------------

I suppose the line '# Default-Start:' to be different on your computer.

No clearly there is a LSB header issue. insserv complaints that it the
initscript 'nfs-kernel-server' tells it, that 'nfs-kernel-server' depends on on
the functionality provided by 'nfs-common'. But since 'nfs-common' is disabled
it can't fullfill the requirtment.

well at least the error message from earlier is gone.

The idea behind insserv and the LSB headers are to provide a system to declare
dependencies between initscripts. Look at the code snipped above it says
'# Required-Start:'.
This means '/etc/init.d/nfs-common' can only function after the
'$portmap $time' are available. '/etc/init.d/nfs-common' by it self also has
such a '# Provides:' so that other initscript can tell "only start me after
'/etc/init.d/nfs-common' is already running".

So this LSB headers are there to managed initscripts and insserv uses them to
create/resemble the start scripts below '/etc/rc[S0-6].d/' depending on the
actually installed services.

you can use:
insserv -v

to manually call insserv. It will tell you the same error messages as during apt
operation until the initscripts are fixed.



So in the end it is possible that insserv complaints that there are unfulfilled
dependencies, but it is still possible to start those services manually. Which
is what you did.
