Subject: [PATCH] lvmstrap: ignore small-sized partitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch changes lvmstrap to ignore βsmallβ partitions. Currently
extended partitions are reported as unused as with a size of 1024
(bytes), and this confuses lvmstrap. Since a very small partition
won't help anyway (below hundred of PE size is not helpful), let's
restrict it to 1GB.
