I could fix most of my issues by purging kde settings.
And fixing the ownership of the home folder.
I could get working iscsi. And now I think I am happy with what is working. Screen tearing is a bit of a issue thanks to Nvidia and my 2 monitor setup, but it isn't as bad as on other oses.
The documentation is rare and the atomic behaviour seems to break my whole Linux work flow.
Which is a good thing I guess. But I can't Google "how to do x on nixos" and get a reasonable answer. I get nothing. Or some weird forums where I don't know what they are talking about.
I will give it an honest try but so far I am upset by the software not working as expected.
And hell your documentation is lacking.
There is a single software center currently in beta to install software with gui. And the nix-env version does work well actually but the configuration.nix install is hardly documented and not intuitive.
I did install vlc. I started vlc. I noticed completely wrong subtitle size. I went to settings and tried to change some and save. Vlc throws an error it can't save the file, permission error.
I install vlc with flatpak. Same subtitle error. I go to the settings, I don't get an error but the settings don't change anything.
Also almost anything i do in the plasma settings doesn't get saved.
And that shit should only be saved in the home folder.
The benefit would be: changing stuff doesn't break it. And if it does you can easily roll back.
Keeping the config file sets up a new installation like the old one without trouble. Somehow I don't think you really need it if you aren't distro hopping but I need it way too much.
Currently the trade offs are too big I think. Programs don't work because of the atomic behaviour.
And the learning curve is steep even for Linux veterans.
Ehhm actually Genocide exactly means wiping them all out.
