What happened?

I'm using Ventoy installed to a SSD to boot Rocky Linux ISOs. It worked just fine for months using Rocky 9.4 but now when Rocky 9.5 was released, the VTOY_LINUX_REMOUNT is no longer working.

My workflow:

• Mount ventoy to /mnt
• Download ISO to /mnt/my-iso-v1.x.x.iso
• Modify ventoy/ventoy.json and set VTOY_DEFAULT_IMAGE to the new ISO.
• umount /mnt
• reboot

The ISOs are made using osbuild-composer from standard Rocky Linux.

Now with Rocky Linux 9.5, I'm getting this error:

$ mount /dev/sde1 /mnt
mount: /mnt: /dev/sde1 already mounted or mount point busy.

I've tried booting in an identical image but based on Rocky 9.4 and it works fine to mount the ventoy partition.

My ventoy.json:

{
    "control": [
	{ "VTOY_LINUX_REMOUNT": "1" },
        { "VTOY_MENU_TIMEOUT": "5" },
        { "VTOY_SECONDARY_TIMEOUT": "5" },
	{ "VTOY_DEFAULT_SEARCH_ROOT": "/" },
	{ "VTOY_DEFAULT_IMAGE": "/myiso-v1.0.130.iso" }
    ]
}

Any updates ? I believe it's happening for other recent linux distros as well.
