Hello,
how is it possible to Modify the boot medium? Some boot media have the option of starting a live / rescue system. Can I add further standard packages to this Live / Rescue System or set certain time zones as standard?
Regards
Ronald
Hi
Have a look at using Kiwi https://documentation.suse.com/kiwi/9/single-html/kiwi/index.html to create your own image, or use Studio Express at https://studioexpress.opensuse.org/
Okay good thank you @malcolmlewis 
I will try it.
Some further questions to https://studioexpress.opensuse.org It looks really cool B) but can I create also iso-Images to boot from DVD-Drive? I see only VM, Raspberry Pi Images?
Hi
Yes, just need to define the image type in your xml file preferences section.

Worth a read as well https://openbuildservice.org/help/manuals/obs-user-guide/art.obs.bg.html
I find a little easier to build locally just need a config.sh, config.xml and root folder…
An example I use to just build a small iso image for testing;
<type image="iso" primary="true" flags="overlay" hybrid="true" hybridpersistent_filesystem="ext4" hybridpersistent="true"/>
