Thx this sounds like the best solution. Definitely trying it out. Idk how well I will be able to do it, Because I didn’t even made those containers myself. I just used proxmox helper scripts. Something came up today and I didn’t have time again, will try it tomorrow.
I know they said the mod is too big for nexus, but why did they choose only gog for the release? Steam has great support for mods in their store. Enderal released on steam just fine.
Now when you install fallout London it uses your fallout 4 install, so you can’t switch between games. If your f4 is on steam you have to downgrade it and disable steam cloud. If they released on steam they could have just make it that people can install the mod only if they own f4. Then they could have just include all files needed in their own install, and wouldnt have to use your f4 game. No downgrading, working cloud saves, both games playable. If they didnt want to pay 100 bucks for steam page, they could have just ask me, I would pay for it.
