Comment 4 for bug 1313513

As a point of interest, this is an `rbdmount` script I use with upstart as a work-around to the mountall issue.

It assumes that the devices listed in /etc/ceph/rbdmap are intended to be mounted locally, and so calls mount on each listed device that appears.

Very much a hack: it'd be more elegant for mountall to not block the boot process.
