[Bjoern Voigt <bjoern@xxxxxxxxxxxxxxx>]

Hello!

I also created a small script for updating my openSuSE iso files with
delta-iso files. The script does not download the delta-iso files
because I download the delta-iso files externally.

But the script applies the delta iso files and deletes the old
files (old iso files, old delta-iso files). The script is especially
useful if you do not have much temporary space or if you want to
re-start an "applydeltaiso" command.

The script header contains an example.

Greetings, Björn#! /bin/bash
