I must say this has been one of the most confusing things I have done this last month. How do i create an offline custom proxmox installation with offline packages where I install proxmox on nvme01n and then give an amount of disks raidz10 (zfs). Have people figured this out? Ai is hallucinating on this and I see alot of useless post on this matter. I do understand that it has its limits but I am soon done. It hasnt been an easy process and I have no idea if there is an official way doing this. But I am building an image with docker -> trixie. Then In same folder I will need post install script, packages and a build script where I use the proxmox 9 iso and also an answer toml script. In the answer toml I install proxmox on nvme. Then it builds the iso takes answer toml, packages and post install/first boot script. Then I am stuck here. if you have question regarding this setup please ask. I will answer you. Even though myself I am confused on how I made it work partly but it took alot of trial and error.
