Why isn't filesystem bigger than 4G bootable
I'm creating a custom ISO based on the official Ubuntu 16.04.
What I'm doing is simple:
1) mount the official Ubuntu iso to /mnt;
2) cp /mnt/install/filesystem.squashfs /home;
3) cd /home && unsquashfs filesystem.squashfs;
4) put my own files into squashfs-root and execute mksquashfs squashfs-root filesystem.squashfs;
5) mkdir iso && cp -r /mnt/* iso/ && cp /home/filesystem.squashfs iso/install/.
In a word, I put my things into filesystem.squashfs and rebuild an ISO file.
To build the ISO file, I execute mkisofs -RJ -joliet-long -iso-level=4 -o test.iso iso/.
At last, I get my ISO named test.iso.
However, this iso is not bootable because I put lots of files into it (the new filesystem.squashfs is 5.3G).
Google told me that it couldn't bigger than 4G.
So, is there a way to make a bootable ISO whose filesystem.squashfs is bigger than 4G?

The limit could be in that version of mkisofs, I suspect.

AFAIKmkisofshas not been in development since around 2002.... There is an actively developed program called xorriso ... Here is the Ubuntu package If you install that program, you can get detailed information regarding your created iso image and the original image using:xorriso -indev my_image.iso -report_system_area....
