Bug 3282 - Mounting from localhost in fstab fails at boot on ubuntu
(http://bugs.gluster.com/show_bug.cgi?id=3282)

Ubuntu uses upstart instead of init to bootstrap the system and it has a unique
way of handling fstab, using a program called mountall(8).  As a result,
glusterfs mounts in fstab are tried before the glusterd service is running.  In
the case where the client is also a server and the volume is mounted from
localhost, the mount fails at boot time.  An upstart job for glusterd is needed
to correct this.

The glusterd.conf file contains the necessary configuration for upstart to
manage the glusterd service.  It should be placed in /etc/init/glusterd.conf
on Ubuntu systems, and then the old initscript /etc/init.d/glusterd can be
removed.

It can also be added to Ubuntu deb packages by placing it in debian/upstart
inside the source package (or debian/glusterd.upstart if the source package
builds multiple binary packages.)

This affects all versions of glusterfs on the ubuntu platform.
