Arch noob
Establishing a backup strategy. I'm using BTRFS with snapper and a pacman hook that creates a new snapshot before each upgrade. With ext4 I used timeshift. Besides that, I save my arch configuration with aconfmgr and my files with borg
-
New machine, same system: Top to bottom vs bottom to top
Since my last cloning I've setup aconfmgr and and systemd-homed. I've also been playing around with archinstall configs to partition the system with encryption how I like. In the future I'm planning to use archinstall and aconfmgr to setup a new system for me and then I'll copy over the backup of my home directory.

Best way to "log" a re-creatable install?

Rebuild a system
Have you tried aconfmgr? In addition to installing packages, it also tracks configurations in /etc and modified files.
- Alternatives to home-manager?

New arch install and partitioning, what's the best way to make backups that doesn't take up a ton of disk space?
For my backup I keep files in my home directory synced with my NAS via syncthing. For my system backup I don't actually backup up my system, I configure my system via aconfmgr and that config is stored in my home directory and synced to my NAS. Using aconfmgr to "backup" my system is extremely space effecient, my aconfmgr config is only 1.7 MB.
-
is there a good way to synchronize the system between different machines?
aconfmgr (in AUR) can be used to save and restore system configurations and installed packages. For user configuration you can use a dotfile manager like chezmoi (in repo).
-
Backup of system and package settings
I know you prefer backing up manually, but aconfmgr might be for you.
-
What do most people forget to do on a new install that's important?
To get something closer to nix on arch I like to use aconfmgr.
-
Is there anything similar to Arch's aconfmgr for Gentoo? A program that can track, manage and restore your Gentoo configuration?
For those who are not familiar with Arch's aconfmgr, well I have not used it before but just saw it in a post. But it seems to be a configuration manager for Arch. It tracks, manages, and restores your Arch Linux OS configuration.

Looking for dotfiles repo examples
This one issue may clear things up, seems like my config is a little outdated: https://github.com/divnix/digga/pull/385

Building a highly optimized home environment with Nix
I'm new to the Nix world, but so far I've come across Divnix's Digga, Numtide's DevShell, and Misterio77's nix-starter-configs.
-
Need for a configuration framework?
There are config templates / configuration helper libraries that try to make this easier, for example digga/devos.
-
(meme) It's a temporary setback really
https://nixos.wiki/wiki/Flakes, especially the “see also” section. If you’re looking to use for NixOS config across multiple hosts, digga (see the repo for example template) is pretty nice for encapsulating a lot of boilerplate.
-
Sharing configuration between NixOS and MacOS
The digga library, while being more complex to use than other solutions here, got a pretty elegant solution for it merged a few weeks ago. Still some cracks that are getting smoothed over, but it seems to work.
-
Best practices for organizing code repository for multiple machines? What about deployment?
I like the concept digga/devos uses (unfortunately their stuff kind of is an overengineered incomprehensible mess): They use: - modules: for modules like in nixpkgs (i.e. stuff that defines options and generates configuration based on that options; are included into every host) - profiles: concrete configuration, can be included to host definitions - suites: sets of profiles (so you can for example have a desktop suite with all your profiles with "desktop" configuration options and apply that to all your desktop computers)

The Curse of NixOS
For the system, I like the devos template:
https://github.com/divnix/devos
The idea of flakes is how you define inputs, and you define the system (and packages, and shell etc.) in the outputs using the inputs. The inputs are git repos which point to other flakes. You can mix and match these as much as you want (see the devos repo for examples) and when you build the derivation, it generates a lockfile for exact commits in that point in time what were used in the given inputs.
You commit the lockfile and in the other systems where you pull your config from the repo, it uses exactly those commits and installs the same versions as you did in your other systems.
This was quite annoying and hard to do before flakes. Now it's easy.
The problem what people face with building their system as a flake is combining the packages so you can point to `jq` from the unstable nixos and firefox from the stable train. I think this aspect needs better documentation so it wouldn't be so damn hard to learn (believe me, I know). Luckily there are projects like devos that give a nice template for people to play with (with documentation!)
Another use for flakes is to create a development shell for your repo, an example what I did a while ago:
https://github.com/pimeys/nix-prisma-example
Either have `nix-direnv` installed, enter the directory and say `direnv allow`, or just `nix develop` and it will gather, compile and install the correct versions of packages to your shell. Updating the packages? Call `nix flake update` in the directory, commit the lockfile and everybody else gets the new versions to their shell.
-
What's the proper way to set up nix / home manager w/ flakes, directory wise?
Yes, I put the repository in ~/nix. My repository is based on devos, but I am thinking of switching to a different setup, because I don't want to depend on a framework which can be an issue in updating.
-
The future of Home Manager and Flakes
I no longer use the official way since I have switched to flakes. I am currently using a devos-based config, which is a boilerplate that depends on a Nix toolchain, but I plan on rewriting the config with flake-utils-plus. You probably can install home-manager using deploy-rs. See the following comment:
