Right, if you update a remote :nixos: #NixOS machine via an #autossh tunnel (that received a minor change) and it gets stopped for the update, you got yourself a problem 😆
Luckily, there is restartIfChanged = false; 😌

I upgraded my lenovo #T490 from #NixOS 24.11 to 25.05 within an hour or so.
I've lost "xdu" (custom package doesn't compile anymore), had to manually download a closed source binary once again, had to manually replace "okular" with "kdePackages.okular" and remove &quot…

#NixOS 25.05 system update (approx. for 4 weeks) took 1h7min on my lenovo #x260 i5 (16GB RAM).
I have no idea why the performance is so poor on that machine in contrast to T490 with same NixOS configuration.
I'll see after I switched back to

Yay, I finally figured out how to build HTML documentation of my custom :nixos: #NixOS options. 🥳
Some thoughts:
- It still contains *all* normal NixOS options (it's a 13MB HTML file...)
- I don't see a way to filter for only my custom options - be it just by regex for example
- It's the documentation of *possible* options, doesn't include the actually chosen val…

Tried switching to #ghostty on both macOS and #NixOS. On macOS, it replaced iTerm2 for me and the transition was pretty smooth. Also worked fine with fish and starship ootb. Just the still persisting SSH issues (which are blamed on ghostty being too new for external applications to recognize it)…

Finally! I was able to install #nixOS back on my work computer. What a delight, everything just works and is declarative, customized to my preference. I really love #KDE #plasma6

Anyone using #JupyterHub (services.jupyterhub.enable=true) on :nixos: #NixOS? Then you should have run into the database migration issue here:

Does someone know if it is possible to use the devenv services with flake-parts?
I would like to only consume the nix modules and use them with flake-parts.
I know that services-flake exists but I want specifically the devenv services.

Troubleshooting infinite recursion is my least favorite #nixos problem.

Okay why tf would it be that `nix profile install git ssh://myurl` always installs a version some commits behind? 😠 `nix profile ugprade` the same.
UPDATE: use --refresh.

Oh wow ​LLMs are just so terrible. 🤦‍♂️

Everyone please don't scare away new people on #fedi . They don't have to use #archlinux to post here #nixos is also supported.

During the last 2 years with #NixOS, I've mentioned multiple times that my system performance is very poor on my backup notebook: Lenovo #X260 with a 2y old crucial 2TB SATA SSD BX500 2.5"
After setting it up with Debian 13 on the 2TB SSD as well as on the original 250GB SSD, I have to say that th…

Today I've been fighting again with this absolutely stupid :nixos: #NixOS bug that dates back nearly 20 years now, which prevents you from naming an executable 'log'. Yes, it is NOT possible on NixOS. 🤦 🤦 🤦 And working around it is beyond frustrating. Fixing it requires a mass rebuild, so it's not that simple. 😩 😂 It's so terrible but also hilarious...

Has anyone provided helper functions with and for one of their :nixos: #NixOS modules? 🤔

Providing helper functions in and for a module
Some (of my) module options would benefit greatly from helper functions for defining option values. An example would be populating services.jupyterub.kernels, which can get quite verbose if you include things like wrapping in an FHS env or custom virtualenv management. Sure, types.submodule exists, but such a submodule is rather suitable for perfectly similar structures with just different values. Instead, something like this would be helpful: { pkgs, config, lib, ... }: { services.jupyterhu…

I don't know why, but on #NixOS 25.05 I'm back again keeping my worktree nice and DIRTY so I can use :gitannex: #gitAnnex'ed files. 🙄

#NixOS driving me nuts right now. Keeps rebuilding coreutils for aarch64-linux when building for my RPi (but it's definitely in the cache, so it has to be some obscure special version deep down), it takes ONE.FRICKING.HOUR just for it to fail on ONE 'test-free' (qemu: uncught target signal 11 (Segmentation fault) - core dumped). 😠
