[Xen-devel] [PATCH] Check for presence of hotplug

[Michael Vrable <mvrable@xxxxxxxxxxx>]

Here's a minor patch to check for the presence of hotplug, which is
needed in domain-0 now for block devices to work.

(Hotplug is included with most distributions, but I've been using a
fairly minimal domain-0, which didn't include hotplug.)

This script should be made executable, but I'm not sure this is
reflected in the patch itself...

Add an install-time check for hotplug.

The hotplug subsystem is currently needed for block devices to work, as
of changeset 6742:e9d01c5dc7b4d6b7cda9ade0d137ddb89bb204cc.  Add a
script to check for the presence of hotplug and warn if it isn't found.
