I am customizing centos iso, i took standard CentOS-7-x86_64-DVD-1810.iso and extract it and custom folder and add my files.
Now i am recreating custom iso with below command
mkisofs -o centos-7-custom1.iso -b isolinux.bin -c boot.cat -no-emul-boot -V 'CentOS 7 x86_64' -boot-load-size 4 -boot-info-table -R -J -v -T isolinux/
its adding all files but not including one file(tar.gz) which has size of 3GB and no error.
in output no error and strange is that from one folder it including all files except this big size file.
is there any restriction?
PS: i am running this command from mac
