Hetzner provides managed web hosting too. For emails I think you need to look for some other provider.

I’ve been a happy customer with joker.com (Germany) for at least 10 years.

I think it’s easier the other way round, find all symlinks and grep the directory you want to move from results.

Something like ‘find /home/user -type -l -exec ls -l {} ; | grep yourdirectory’ and work from there. I don’t think there’s an easy way to list which symlinks point to any actual file.

Exactly. You can build rules with ufw and view them on iptables. Maybe the one thing ufw does better out of the box is persistent rules and simpler “firewall on/off” switch, but specially on this particular question I don’t think they matter.

And me.

They are excactly what the name implies. Testing is generally pretty good, but it’s still testing. And unstable is also what the name implies. People, myself included back in the day, run both as daily drivers, but if you want rock stable distribution installing unstable revision might not be the best choise.

Debian. I’ve had installations which went trough several major version upgrades, I’ve worked with ‘set and forget’ setups where someone originally installed Debian and I get my hands on it 3-5 years later to upgrade it and it just works. Sure, it might not be as fancy as some alternatives and some things may need manual tweaking here and there, but the thing just works and even on rare occasion something breaks you’ll still have options to fix it assuming you’re comfortable with plain old terminal.

1. VM running on a proxmox host. Tips: make sure you know your backups are in a state you can restore data from them.
2. Nightly backup via proxmox to Hetzner Storage box with 2 day retention. I’d like a local copy too but I don’t currently have hardware for it.
3. Don’t know. Personally I have a DNAT rule on firewall and my instance is directly open to the internet. You might not want that and I might not recommend it, but right now, for me, it works. I’d need to look in a VPN solution for android I could replace the current ‘open for all’ situation.

How much RAM your system has? Zfs is pretty hungry for memory and if you don’t have enough it’ll have quite significant impact on performance. My proxmox had 7x4TB drives on zfs pool and with 32 gigs of RAM there was practically nothing left for the VMs under heavy i/o load.

I switched the whole setup to software raid, but it’s not offically supported by proxmox and thus managing it is not quite trivial.

I mostly use battlestar galactica ship names for my own hardware, but it’s been mixed with boring ‘<function>.mydomain.foo’ names as well. I should rename a bunch of stuff around and include them in my DNS.
