all versions of sysinstall
>Description:
for automated installations it is often necessary to delete
the previously existing fdisk partitions (slices) from the
script, otherwise the results are not as expected.
>How-To-Repeat:
a previously fdisk partitioned disk prevents successfull
re-partitioning of a disk.
>Fix:
introduce a new variable for sysinstall "deletePartition".
For the moment it is only possible to give a argument of "all",
which means to delete all slices. For deleting of a specific
slice, it would be necessary to figure out how to a access it.
The patch applies to current and stable. Man page update included.
