This must have changed with 23.04 or something then, because when I set up my home server a little over a year ago, ZFS as root was not only not a part of the install, but also heavily recommended against as something that could be hacked in. Basically you could do it, but you shouldn’t was my impression. I ended up doing EXT4 as root, then mounted my ZFS storage in my home directory.

Ubuntu and many other distros do not come with ZFS support out of the box due to licensing, so it is not recommended to use ZFS for the root filesystem.

All of my passwords are in Bitwarden and important ones are shared with my wife who has her own Botwarden and has shared her important passwords back with me. If one of us goes, the other will have access to everything. I don’t (yet) have any descendants to inherit anything of importance, so I’m not worried about anything beyond my passwords so that if something happens to me, my wife can manage all of the accounts for bills, banking, communication, etc.

If/when I have children, I will likely make a new plan that builds on what I already have, with directions to access my password vault that can be given to my brother and his husband and my parents, should they outlive me and my wife. With my passwords, everything else of import is accessible. Thankfully, my brother is very tech savvy, so if my wife and I both go, I can trust him to be able to log in to everything and pull important media down.

You still need to scan individual plants resources or animals to get the Surveying perk upgrades, which gives you better zoom on the scanner, which can be useful sometimes.

Https://5e.tools/ has a plugin for Foundry that lets you pull basically everything from every source into Foundry. Oh and you can host your own 5eTools instance just in case the site gets nuked from orbit by Wizards

They can only be connected to your router if the router has POE support. If it doesn’t, you will need a separate switch that has POE ports. Many POE cameras etc are sold with power injectors. You plug the Ethernet from the router into the injector, plug the injector into a wall outlet, then run Ethernet from the injector to the device. If you don’t want to get a whole new switch with POE ports, you could get POE that way.

Cinnamon has an official Ubuntu flavor now. I would recommend that over Mint, since mint is LTS-only. You can also do KDE-Plasma, but my personal preference is Cinnamon.

Except that the old PC is probably less efficient at a lower clock than an AR based consumer router. You’ll get more performance and features, but it will be more expensive to run.
