Does anyone use Ventoy to install OMLx?

OK this is bizzare but I think I have something that works.

  1. Do as @Ojoyer says: in Konsole, cd to “/run/initramfs/omdv/LiveOS ”,
    then
    cp squashfs.img /live
    You have to do this step immediately after booting the ‘Live’ ISO or the folder /run/initramfs/omdv/LiveOS will either disappear or somehow not get recognized. After doing that cp then that folder will disappear so next:
  2. $ sudo mkdir /run/initramfs/omdv/LiveOS
  3. $ sudo cp /live/squashfs.img /run/initramfs/omdv/LiveOS
  4. To check:
 $ ls -la /run/initramfs/omdv/LiveOS
total 2867796
drwxr-xr-x 2 root root         60 Oct 19 20:30 .
drwxr-xr-x 3 root root         60 Oct 19 20:29 ..
-r--r--r-- 1 root root 2936623104 Oct 19 20:30 squashfs.img
  1. Install OMLx

This does not make sense but what I keep seeing over and over is that something is causing the directory /run/initramfs/omdv/LiveOS to disappear or not be recognized. I have in the last 2 days make 8-12 install attempts with an OMLx iso booted off of Ventoy.

So after doing all the steps above I did get iso #3364 booted from Ventoy to install. I will want to do a few more tests to confirm this before I say this problem is solved.

As far as I can see Calamares looks for squashfs.img in /run/initramfs/omdv/LiveOS so /run/initramfs/omdv/LiveOS/squashfs.img must exist for there to be a successful install. This is not optional.

The larger issue seems to be wtf is causing that folder to be there and then if you do the cp to /live or try to do an install that folder disappears or is no longer recognized. That is bleeping weird.

Edit: It is likely that the above steps would work with most if not all current OMLx isos.
