[SOLVED] persistence difficulty

[captain-sensible]

The label is something of the filesystem(ext4/xfs) not the partition.
casper-rw is the default label used by ubuntu and some distros based on it.  During boot the system will search for a block device with casper-rw label, if found, then it will mount it as the persistent envrioment.

 ok i checked my ventoy.json syntax is Ok .

i formated persistence.img using :

#  mkfs.ext4  -O 64bit  -L casper-rw persistence.img

//on boot it will boot iso no problem but not picking up nor giving option for persistence ?
