[SOLVED] persistence difficulty

[captain-sensible]

1. ventoy.json must under ventoy directory,  that is  /ventoy/ventoy.json    yes, you should rename the default persistence.img to what you want.
2. maybe something about the file encoding?

if CreatePersistentImg.sh just creates a file called persistence.img and it has caused me an error, then in theory i should just be able to use the command line to create my own persistence.img

i have utility falocate and so created raw.img via:

# fallocate -l 1G pesistence.img

which i could now format to ext4

i'm a little confused with the mention of "label" casper-rw

if you format a usb sticj for instance say with gparted and give it a label say "spare" then the usb sticj becomes "spare" so wondering where a label "casper-rw" comes into it yet the file is still named "persistence.img"?
