Subject: [PATCH 201/208] libparted: remove old partitions *first* before
|
|
adding new ones
|
|
|
|
"libparted: avoid disturbing partitions" put the remove of the old
|
|
partition in second pass. If you simultaneously removed partitions 1
|
|
and 2, and created a new partition #1 that overlapped the previous second
|
|
partition, the sync would fail because it would try to create the new,
|
|
larger partition #1 before removing the old partition #2.
