[Bug 798963] Re: Incorrect upstart dependencies cause race conditions with NFS mount points

[david]

The problem seems to be related to the fact that I have configured my
network interface statically using /etc/network/interfaces:

auto eth0
iface eth0 inet static
	address	192.168.0.20
	netmask 255.255.255.0
	gateway 192.168.0.1

When this interface gets configured, it is in the "UP" state, but it
takes 1-2 seconds to get into the "RUNNING" state. The effect is that as
soon as the interface enters "UP" state, the event "net-device-up" is
fired, upon which mountall tries to mount the network shares. Because
the interface is not "RUNNING" yet, it does not send/receive data, and
mounting fails.

Adding a delay in /etc/init/mount-net.conf makes the problem go away, as
does not using /etc/network/interfaces for network configuration.

I'm not sure if this also solves the GDM autologin problem, I'll have to
try some more.

Title:
  Incorrect upstart dependencies cause race conditions with NFS mount
  points

Status in “mountall” package in Ubuntu:
  New

Bug description:
  Binary package hint: mountall

  I use an NFS mounted home directory (in /etc/fstab: 192.168.0.2:/home
  /home      nfs
  defaults,tcp,async,noatime,rsize=16384,wsize=16384,_netdev) and
  automatic login in GDM. Usually, /home is not mounted when GDM tries
  to log in, causing various errors due to the non-existing /home
  directory.

  If I try again a few seconds later, all works fine (because by then
  /home is mounted).

  I think the upstart dependencies are wrong:
  - /etc/init/mountall.conf has no dependency on network, so it only mounts local file systems. However, it emits "filesystem" and "remote-filesystems"
  - /etc/init/gdm.conf depends on "filesystem" (obviously assuming that "filesystem" also includes network filesystems)
