+# This script is meant to be executed from Fedora install ks.cfg in the pre-section
+# It should reside on the Partition named OEMDRV formated as BTRFS or EXT4
+# The Location inside the OEMDRV- Partition should be /ks_base_profiles/basic_pre_script.inc
+# When running from ks.cfg pre-section, the OEMDRV should be mountet by Anaconda to /mnt/tmp
+# It will be run as root and will use sh to execute, the pre-section should look somewhat like this:
+# %pre
+# /bin/sh /mnt/tmp/ks_base_profiles/basic_pre_script.inc
+# %end
+
+# The Script will search for the drive with the Partition OEMDRV on it and
+# REMOVE ANY OTHER PARTITIONS ON THAT DRIVE
+# As Anacondas scripts are non interactive, it will do so without asking or stopping.
