Hi, I have several clients in a lab getting /home via nfs with the line
below.

  nfsserver:/home /home nfs defaults,nolock 0 0

After upgrading to squeeze and dependency based system for init
scripts all clients stall
for about 2 minutes while running /etc/network/if-up.d/mountnfs.
When finishing boot sequence, I have to run mount -a manually to mount the shares

Debugging the script with set -x shows it stalls on
  mount -a -tnfs

After inspecting the script I saw that flag start_nfs is not set to
yes when using nolock option with below explanation

# NFS filsystems normally require statd and portmap. However,
# if nolock is set, portmap and statd are not required for this
# file system

However start_nfs=yes is needed to run 
   /etc/init.d/portmap start
   /etc/init.d/nfs-common start

When I remove nolock from /etc/fstab, start_nfs is set to yes and booting is smooth,
 but I have other issues so i cannot remove it.

nfs-common service due to dependency based system is started after networking service
which triggers /etc/network/if-up.d/mountnfs 

I think that mount -a -tnfs cannot succeed 
if nfs-common service has not started in the client and

So it needs to be started in this script to mount correctly even if nolock option is set

Bottom line, I think that start_nfs flag should be set to yes
even when clients mount nfs shares with nolock

  What is your opinion?
