Hello,
The Lorax tool is used for creating boot.iso including initrd. The same
tool is also used for creating Fedora and RHEL.

Hi, Jirka! 
You can start here for lorax:  https://www.brianlane.com/creating-the-anaconda-bootiso-with-lorax.html

My quick en-tutor draft can be found here:  https://github.com/Frodox/bitthinker.com/blob/master/content/en/develop/how-...  , but it is still in progress and ru-version in priority (and with more examples). You can write me/here if you have any questions in progress.

Regards,
Vit Ry.

Hi Vit Ry,

Thank you for links. It's nice to have step by step tutorial. I will
