[Bug 765545] Re: nfs mounts in fstab block boot at "S or M" prompt

[Steve Langasek]

bwalex, is this issue still reproducible in 12.04 if using hostnames in
/etc/fstab?  I've been using hostnames forever for my nfs mounts, and
have never seen these problems at boot.

Title:
  nfs mounts in fstab block boot at "S or M" prompt

Status in “mountall” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: mountall

  I have the following two lines in fstab:
  nasi.local:/secure/alex         /home/alex/secure       nfs     defaults,rw,exec,user,nobootwait        0       0
  nasi.local:/data                        /home/alex/data         nfs     defaults,rw,exec,user,nobootwait        0       0

  On every boot I get prompted with the famous "S or M" prompt to manually mount or skip the mounting. The shares themselves ARE always available. Skipping doesn't work for other reasons (see [1]), nobootwait doesn't work for even other reasons ([2]). The only way to get the system to boot is to manually fix the issue by pressing "M" and then starting dhclient manually:
  # dhclient -v eth1
  After that the boot can continue by simply exiting the emergency shell. This is clearly an issue with nfs mounts being tried before setting up the network, or at least running dynamic network configuration (i.e. DHCP). 

  Also note that this happens reliably on every boot, so a race is
  unlikely. I also don't have /var as a separate mountpoint.

  Just for completeness sake, my complete fstab:
  % cat /etc/fstab | grep -v ^#
  proc            /proc           proc    nodev,noexec,nosuid 0       0
  UUID=e278f6aa-8fba-47be-880b-53bbce04a9d8 /               ext4    errors=remount-ro 0       1
  UUID=c842351a-aa7c-478a-a58f-f671ca6e6858 /extra          ext4    defaults        0       2
  UUID=79f60f9a-a507-41d7-b00b-c831bd3ba892 /opt            ext4    defaults        0       2
  UUID=373f64a7-04d0-4d21-94dc-8b08c3fef2b9 none            swap    sw              0       0

  nasi.local:/secure/alex         /home/alex/secure       nfs     defaults,rw,exec,user,nobootwait        0       0
  nasi.local:/data                        /home/alex/data         nfs     defaults,rw,exec,user,nobootwait        0       0
  UUID=3a094e37-2689-435d-8a00-447274664320 /home ext4 defaults,user_xattr 0 2

  
  And for even more completeness, the /etc/exports on the server (debian squeeze):
  /data   192.168.0.0/24(rw,no_subtree_check,async,no_root_squash)        192.168.2.0/24(rw,no_subtree_check,async,no_root_squash)        10.0.1.0/24(rw,no_subtree_check,async,no_root_squash)
  /secure/alex    192.168.0.0/24(rw,no_subtree_check,no_root_squash)      192.168.2.0/24(rw,no_subtree_check,no_root_squash)              10.0.1.0/24(rw,no_subtree_check,no_root_squash)

  
  Kind Regards,
  Alex
