Describe the bug

When booting from netboot.xyz http://boot.netboot.xyz/ipxe/netboot.xyz-snponly.efi and selecting Ubuntu 23.10 as Live CD, i get an error: /cow format specified as 'overlay' and no support found. This was recently also described in the ubuntu launchpad bug tracker.

Edit: Booting the Ubuntu 23.10 Network installer from netboot.xyz works

To Reproduce Steps to reproduce the behavior:

1. Boot from iPXE and netboot.xyz
2. Select Live CDs > Ubuntu > Ubuntu 23.10 > KDE version
3. wait until all files have been loaded and the error appears

I've also tried to use the fix recommended in the bug (in my lab enviroment - removing the panic in scripts/casper in initrd) but that just fails too.

kernel parameters as of now are:

kernel ${kernel_url}vmlinuz${sas_token} ip=dhcp boot=casper netboot=url url=${squash_url} initrd=initrd locale=${language} ${cmdline}

Expected behavior

The boot is successful with these current settings.

Screenshots

Default iPXE boot from netboot.xyz

Issue with modified scripts/casper according to the launchpad bug:

Edit: booting the network installer for Ubuntu 23.10:

Additional context

I have a seperate lab that I can test custom kernel parameters / initrd / vmlinuz files.

This is probably not going to be resolved as the support just has been removed in main.
