What is that spike in the wall?

Where is the shower drain??

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.

Thx for providing some alternative. I think I will still try to first make it work with mount points and local users. But I appreciate your post and will keep it in mind if I need to use it later.

I was just about to write this… Proton is cool, but I only use mail from them. All my other services are independent from each other, and soon I will be self hosting most of them.
