Subject: [PATCH 32/36] parted: fix the rescue command
|
|
|
|
The rescue command often failed to locate a filesystem due to it
|
|
leaving cylinder alignment on, which snapped the allowed bounds
|
|
of the filesystem down to the next lower cylinder boundary,
|
|
causing the detected filesystem to be rejected due to not fitting.
|
|
|
|
(cherry picked from commit e09c30fb53179319ba1543813b5b4024e923b795)
