HOWTO: Bypass the 4GB filesize limit in Refractasnapshot

Hello Everyone

I finally found a way to make to make ISO snapshots that can be larger than 4GB.
I had this problem for a long time that i would get an Error during the snapshot progress because i have a lot of packages installed on my system.
I know some folks have had the same problem so i thought i'd share the solution to this.

For this to work one has to modify the xorriso command in /usr/bin/refractasnapshot,
my code may differ from your version, the important thing is to add the -iso-level 3 option

xorriso -as mkisofs -r -J -joliet-long -l -iso-level 3 -isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -partition_offset 16 -V "$volid"  -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o "$iso_dir"/"$filename" live/ 

and thats all
i now have a 4.2 GB large ISO file smile
