[Xen-devel] [PATCH OSSTEST 1/3] Debian: erase-other-disks: add a log() helper

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Writing it out each time is too verbose.

At the same time log the set of devices present before and after each
batch of erasing, with a udev settle before the second to ensure any
changes to /dev have happened.
