Soap boxing here but I feel these kinds of use cases is what NixOS is built for.
Declarative config to setup the system, users, and apps.
Declarative and customizable impermanence exactly how you want it.
I use Tails as well but NixOS is my daily driver. Anything not marked explicitly to persist is dropped each reboot. I’m the only user so I keep the last 30 days of non persisted data for like a power outage but that’s something I had to go out of my to setup for my use case.
This is why we trust but verify. Thanks mom for teaching me that cruel lesson of unplugging the phone cord to get me to bed (dial up days). It lasted about a week before I caught on you always came up from the basement before bed.
I’m so glad you never noticed I swapped my line with the guest bedroom. Also glad that ancient block in the basement could be hand wired.
For our lower environments we use rsync like the author but skip the pipeline altogether. The servers have a watch script to restart when files are rsynced. We then have a local watch script that rsyncs on file changes.
Relatively instant deploy (2-5s) whenever a file is saved.
Good call on a simulated failure. When I first set it up, it was LVM/BTRFS or ZFS as my top choices. It was a coin toss at the time because I hadn’t built this sort of setup before.
I use immutable nixos installs. Everything to redeploy my OS is tracked in git including most app configurations. The one exception are some GUI apps I’d have to do manually on reinstall.
I have a persistence volume for things like:
I have 30 days (or last 5 minimum) of system rollbacks using BTRFS volumes.
The personal files are backed up hourly to a local server which then backs up nightly to B2 Backblaze using rclone in an encrypted volume using my private keys. The local server has a mishmash of drives in a mirrored LVM setup. While it works well for having mixed drives, I’ll warn I haven’t had a drive failure yet so I’m not sure the difficulty of replacing a drive.
My phone uses the same flow with RoundSync (rclone + GUI).
Git repos are backed up in git.
Logs aren’t backed up. I just persist them for debugging and don’t want them lost after every reboot.
Caches/Games are persisted but not backed up. Nixos uses symlinks and BTRFS to be immutable. That paradigm doesn’t work well for this case. The one exception is a couple game folders are part of my personal files. WoW plugin folder, EvE online layouts, etc.
I used to use Dropbox (with rclone to encrypt). It was $20/mo for 2Tb. It is cheaper on paper. I don’t backup nearly that much. Backblaze started at $1/mo for what I use. I’m now up to $2/mo. It will be a few years before I need to clean up my backups for cost reasons.
The local server is a PC in a case with 8 drive bays plus some NVME drives for fast storage. It has a couple older drives and for the last couple years I typically buy a pair of drives on sale (black Friday, prime day, etc). I have a little over 30TB mirrored, so slightly over 60TB in total. NVME is not counted in that. One NVME is for the system, the others are a caching layer (monero node) or temp storage (transcoding as it also my media server).
I like the case, but if I were to do it again, I’d probably get a rack mountable case.
I’ve been getting weird walking instructions. Like 6 min walk is +30 to avoid some invisible barrier.
Download 5 seasons of some show from multiple sources or some artist’s entire discography, and want to normalize all the file names? It is way easier in the terminal.
I’ll check this out, but I use https://github.com/stevearc/oil.nvim for such tasks as I have nvim’s full suite of editor commands to rename all the files way faster than I could in a GUI. I’m sure there are GUI apps to perform a similar task, but I already know how to use nvim.
My work laptop is a Dell Precision. It was a “data science” model that came with Ubuntu. Wiped Dell’s modified Ubuntu and put vanilla Ubuntu on it and now running Nixos. Works great. There was a weird period when using triple monitors with their dock had an intermittent issue on boot where resolutions and monitors were not being detected. Cause was Nvidia drivers. It eventually got resolved and it was easy enough to rollback the drivers to one that worked.
Won’t auto update but you could add the upgrade command to a login script or something.
Won’t lie, nix has a high learning curve to get the most out of it, but installing a single app is pretty simple.
Most startups I’ve applied to are Linux friendly.
I currently work for a fortune 100 and managed to get a Linux machine purchased as a “lab” machine.
I’m fully in control. IT doesn’t even know it exists. I’m not allowed on the corporate network, but I managed to get some internal corporate access through another department’s lab network (IT sanctioned) that has a VPN with a few routes to things like ticketing, time cards, and our internal wiki. Most of the stuff I need to do my job is in AWS and we are allowed to add home IPs to the security groups.
IT still gives me a MacBook. I use it like once every 6 months.
nixos-unstable is the only thing I will use currently.
I’m running bleeding edge stuff like the latest kernel, Hyprland nightly, my own “shell” built from Gnome components and lots of custom stuff using GJS (Gnome JavaScript).
If you get one, and you are free to do whatever on it, encrypt your drives like your job depends on it. I have a memorized passphrase, pin protected hardware key, and a key in TPM. No biometrics.
As far as other nice things to have:
I work in software dev as FYI. For the few issues I have, my team has more issues getting stuff working consistently on macOS for our project. I used that as a justification when requesting the laptop: my dev environment should closely match our runtime environment. Most of that is moot now since we use Nix flakes in our repos for local dev envs.
Yeah I don’t want locally deleted media (to free up space) to sync those deletions to my remote.
My crypted remotes wrap a B2 Backblaze one which doesn’t delete, just hides. Periodically I go clean it up.
You are correct, fixed!
https://github.com/newhinton/Round-Sync. Not in any app store and have to download and install from GitHub.
It is an Android wrapper around rsync rclone.
Setup a remote, setup tasks, and setup triggers. Mine syncs every night. It supports encrypting with your own keys. Large number of remotes supported from self-hosted to cloud.
I use rclone and the Round Sync Android client.
Supports a ton of back ends, self hosted, and commercial options. You can transparently encrypt with private keys you control.
I personally use B2 Backblaze for storage.
My phone backs up every night and Round Sync pushes them to B2. On my desktop I can mount as a volume. I can also access my storage from my phone going the other direction.
I’ve done the same using SFTP if I don’t want the overhead of persistent file storage.
It does not support indexing or previews for searching or finding say a photo. You can put whatever you want for data. So I have caches, indexes, and thumbnails that work in Linux. I can’t really make use of those on my phone though.
Rclones bisync feature is also a bit dangerous when I tried to use it a year ago. I more than once “deleted” everything. B2 doesn’t delete by default, just hides, so I was able to recover. I now do unidirectional syncs from my machines to different buckets until I’m motivated to investigate a proper 3-way merge solution.
I use Nix, even on my Ubuntu machines, to install tooling in my user profile.
Nixpkgs unstable stays pretty up to date. The few I want something on release day or bleeding edge nightlies, I override the derivation source. I use nvfetcher to pull the latest release or head of the default branch as part of my update routine.
I’m pretty new to Nix, so its been slow integrating into my workflow, but I plan to start integrating flake’s into my repos. My team seems to have constant issues with keeping their tooling up to date which breaks things locally from time to time.
If the curriculum format teaches students to be test takers, I’d give them extra points for working smarter.
If my job gave me work while on my vacation, I’d be talking to the labor board if they didn’t pay me at my consultation rates.
Anecdotal, but I only see OpenWRT out of the two in commercial products which hints to me its better supported (e.g., security patches and feature support).
Kevin Sussman is going to do the prequel/reboot.
No. Its all text file config. You wouldn’t use live CD mode. You define your own how you want it to work.
Its a steep learning curve so if looking for off the shelf solutions, don’t use nix. If you need something custom but through a single config paradigm, nix is awesome.
