What happened?

• Instruction in document:

Distros | Tested ISO | Label | Notes
Fedora | Fedora-Workstation-Live-x86_64-33-1.2.iso | vtoycow | Need to add selinux=0 in the boot option

• Command executed – which i conceived is valid when aimed to apply to a Fedora Linux disk image; sh CreatePersistentImg.sh -s 16 -t xfs -l pysyvyys.

Investigating the minimal valid value of persistence size, leads me to conclude that it is 16 MiB. That minimal value may be worth a mention in the document and the README file of the Ventoy installation archive for Linux since specified values superior to null and inferior to that value, cause those messages.

# sh CreatePersistentImg.sh -s 1 -t xfs -l pysyvyys
Invalid size 1
