Subject: [PATCH] Round down to nearest MiB value when writing ks parittion
|
|
|
94d765 |
info.
|
|
|
94d765 |
|
|
|
94d765 |
On s390x in particular, some partition alignment issue is causing fractional
|
|
|
94d765 |
sizes to be reported. Pykickstart doesn't take anything except int values for
|
|
|
94d765 |
partition info, hence the call to roundToNearest.
|
|
|
94d765 |
|
|
|
94d765 |
This change only affects the data that is written to ks.cfg.
