After a change

This is a nixos configuration repository. It is personalized for me. Most of the configuration
describes how my machine is set up. Whenever we make changes here, make sure to understand
the consequences of the changes to the operating system.

An example is, when you remove a package from the systemPackages, make sure to explicitly
note that in your summary at the end, that package will no longer be installed.
# After a change
You can use the
```
nixos-rebuild -I zsedem-config=(realpath .) dry-activate
```
oneliner to test our changes.
ALWAYS check the output of the command. and see if our changes need to be fixed.
The expected output for a successful run is
> Failed to start transient service unit: Interactive authentication required.
> Error: switch-to-configuration must be run as the root user
> warning: error(s) occurred while switching to the new configuration

Because we don't run the command with root priviliges we get this output and it is fine.

NEVER offer to run the command with root priviliges. (meaning: do not offer to run commands with `sudo`)

Check ./Readme.md, if it needs to be updated. Only update the readme if we make changes to something general, like something with nixos options.

Offer to make a git commit after we did a meaningful change. Include the whole message, like this:
```
git commit -am "<message>"
```
where your `<message>` should be a meaningful description of the change.
