Subject: [PATCH] growpart: fix bug occurring if start sector and size were the
|
||||
same.
|
||||
|
||||
The existing sed expression would erroneously change the start sector
|
||||
of a partition, rather than the size, if the start sector and size
|
||||
were identical. This commit modifies the sed expression so that it
|
||||
will only operate on the final match in the line.

||||

||||

|
||||
(cherry picked from commit 7b11ac4d3abe16525639cff9198f5e7f8303280b)
