libparted: fix snap radius so that it is using half (#665496)
|
|
|
|
The snap radius didn't match the documentation, it has been
|
|
using +/- unit size instead +/- 0.5 * unit (eg. 500KB for a MB
|
|
unit). This caused problems when specifying 1MB, 1GB, etc. as a
|
|
partition start or end resulting in partitions being created
|
|
that were nowhere near the specified size.
|
|
|
|
Only revert to the old behavior if cylinders are used in order to
|
|
give parted more flexibility when snapping the partition start/end.
