Hi,

Thanks for the info looks promising.
What kind of file system did you use for your test?

Happy new year,
Angelos

hey All, Angelos,

incidentally i just came across Ventoy[1] via the Qemu Advent Calendar[2], a 
usb stick boot manager that boots ISOs from an otherwise usable data partition. 
it supports exFat, NTFS (to name cross platform candidates) among others so 
there is actually no 4GB file size limit.
just booted osgeolive-14.0alpha3-amd64.iso with Ventoy 1.0.31.

where there is a will, there is fun - to be had.. ede

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
