Hi,

The limitation is not actually the iso format but the squashfs filesystem for the live system. When that goes over 4GB, the file cannot be stored in the filesystem the usb/iso uses.

More details here:

Hi Angelos

Just a quick question about the ISO size limit that has been bugging me
last night.

How does projects like Scientific Linux or RHEL manage to get ISOs of more
than 4GB?

I think that the aim of the OSGeoLive project is to fit the ISO on a DVD,
am I correct?

If I may be presumptuous, why doesn't the OSGeoLive project start moving
away from a DVD ISO, to an iso that can run only from USB, or is this
limitation of 4GB a Ubuntu issue?

Please correct me if I am wrong.

Pieter
