btrfs already supports this using subvolumes but you have to install the OSes manually (no installer supports this OOTB afaik)
however Fedora uses btrfs with two subvolumes (root and home) by default but I haven't found a way to install it without formatting the root filesystem though.
Contrary to Turkish, Estonian, Latvian and Hungarian are all EU official languages. That means that all EU legislation is legally required to be translated to these languages and it is readily available in all these languages for free to train the AI model for translating to those languages.
