#cd /home/jay/modified_files

 /home/jay/modified_files

Where /home/jay/modified_files is the folder used to store files extracted from Leap-16.0-online-installer.iso.
The above command is about to create a bootable ISO similar to Leap-16.0-online-installer, sadly the command returns error message:

xorriso 1.5.6 : RockRidge filesystem manipulator, libburnia project.

Drive current: -outdev 'stdio:Leap-16.0-online-modified.iso'
Media current: stdio file, overwriteable
Media status : is blank

xorriso : UPDATE :     350 files added in 1 seconds
xorriso : aborting : -abort_on 'FAILURE' encountered 'FAILURE'

It shows /usr/share/syslinux/isolinux.bin cannot be found, but it is really there.

#ls -l /usr/share/syslinux/isolinux.bin
-rw-r--r-- 1 root root 24576 Nov  7  2024 /usr/share/syslinux/isolinux.bin

Why I failed to create the ISO?

2

If you read the mkisofs man page, it quite clearly says

The pathname must be relative to the source path and inside the source tree specified to mkisofs.

3

What is source path and what I have to install to get it work?

4

Whatever the CD content is taken from.

6

Yes, then copy /usr/share/syslinux/isolinux.bin to /home/jay/modified_files, change -b to -b isolinux.bin. Thank you very much for you reply.

7

I have made the ISO, but when it is booted, says:

ERROR: No configuration file found
NO DEFAULT or UI configuration directive found!

8

You obviously need to provide syslinux configuration if you intend to use syslinux.

9

Did you copy to a partition on the device or direct to the device??

10

How to create a syslinux configuration?

11

Start with reading syslinux documentation. Do you expect me to replicate it here?
