Bug#780941: mdadm.conf: missing explicit hotplug POLICY

[Chris]

Package: mdadm


Some lines need to be added to the installed mdadm.conf,
to explicitly cover/enable the new hot-plug feature configuration:


--------


#### automatic hotplug action policy

## allow automatic re-adding of removed devices when plugged back in
## (requires a write-intent bitmap)
#
POLICY domain=default action=re-add


## automatically use devices as new spares (enabling rebuild)
#
# POLICY domain=default action=spare
