[Bug 1223745] Re: Dependency resolver causes hang on boot

[Launchpad Bug Tracker]

This bug was fixed in the package mountall - 2.51

---------------
mountall (2.51) unstable; urgency=low


  * Fix tagging of filesystems to not have local/remote inheritance
    overridden; otherwise we will mis-tag various mounts and deadlock the
    boot.  Also fixes an inconsistency with the inheritance of
    'bootwait'/'nobootwait' flags depending on the order of mounts in
    /etc/fstab: we now always treat the 'nobootwait' flag as applying to
    submounts. LP: #1223745, LP: #1153672.

Title:
  Dependency resolver causes hang on boot

Status in “mountall” package in Ubuntu:
  Fix Released

Bug description:
  After upgrading to version 2.50 I had my server hang on boot without
  any useful messages. I could track this to a NFS type mount in fstab
  which is mounted under /home and that is another mounted fs in fstab.
  Like

  /dev/xxx        /home          ext4  defaults          0 2
  xxx:/srv/img /home/img nfs    ro,nfsvers=3  0 0

  Verified that with mountall v2.49 this works (kind of as it seems to
  be done first time when network has not finished setting resolv.conf
  from the info DHCP returns). But at least boot finishes and by the
  time one can log in the nfs mount is done.

  Unlike with version 2.50 which either hangs, or when the mountpoint is
  moved somewhere under /, it boots but never mounts the NFS filesystem.

  Since one of the bigger changes from 2.49 is trying to do those
  dependant mounts in the right order I suspect this caused the current
  situation.
