Bug#689605: multipath-tools: no default multipath.conf

Package: multipath-tools
Version: 0.4.8+git0.761c66f-10
Severity: normal

Since the multipath-tools package includes no standard multipath.conf, multipathd will grab any new block device. This can lead to surprising and hard debug effects.
e.g. attaching a device in a XEN dom0 domain will render the device inaccessible. This corrupts xen-utils-4.1 since xend will attach the boot device locally for pygrub, but can't release it properly because multipathd has it.

I suggest supplying at least a minimal multipath.conf that blacklists the most dangerous devices by default.
