[OSGeoLive] Disk (ISO) size limitations

[edgar.soldin at web.de]

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
