Question to DEV team (Ver 2.4.4) - builder-common.sh - memstick option

[fabricioguzzy]

Hello DEV Team,
Is there any technical reason for changing the builder-common.sh script (create_memstick_image section) to generate an ISO instead of an img file?
I see the script is now using the "mkisoimages.sh" and not the usual "make-memstick.sh"
What would be the reason for that?

Thanks and Regards,
Fabricio.
