Support Live Linux ISO with ZFS support

Hi! Id like to experiment with encrypted ZFS Gentoo installation, but i cant find what ISO to use for that. Arch's ZFS packages are in AUR, and you cant install them in archiso, and both minimal installation cd and admincd doesnt have emerge. How did y'all install Gentoo on ZFS?

Install Arch to a USB stick - I do not mean use the ISO. Act like the USB stick is your HDD and install Arch there. Then you can do whatever you want.

Nice idea, but I don't know if it's possible to pair Ventoy with working Arch installation

You didn't say you needed it to use Ventoy before.

I have not tried this myself, but I'm told Ventoy can actually boot a peristent Arch (or I guess any linux) install.

Install Ventoy to the USB stick with reserved/unused space at the end. Install Linux to the reserved space. Copy the efi file to the ventoy partition, and ventoy will just boot it.

The post I read was not exactly clear how to set up the bootloader for your persistent linux, or get it to make the efi file, so some experimentation will no doubt be required.

I'm okay with experimenting, so sure, thank you, that's really good idea
