**🚨 issue (security):** Consider the security implications of enabling 'insults' and verbose sudo logging.
Ensure 'Defaults insults' is appropriate for your environment. Secure and rotate /var/log/sudo.log to prevent exposure of sensitive data.
</issue_to_address>
### Comment 2

</code_context>
<issue_to_address>
**issue (bug_risk):** The fail2ban jail for SSH uses /var/log/auth.log, which may not exist on all NixOS setups.
NixOS typically uses /var/log/messages or journald for authentication logs. If /var/log/auth.log is missing, fail2ban won't work. Please verify the log path or use systemd-journal integration.
</issue_to_address>
### Comment 3
<location> `modules/performance.nix:61` </location>
<code_context>
+ # Power management for better performance/battery balance
+ powerManagement = {
+ enable = true;
+ cpuFreqGovernor = "schedutil"; # Better than ondemand
+ };
+}
</code_context>
<issue_to_address>
**issue:** Using 'schedutil' as the CPU frequency governor may not be supported on all kernels.
Verify kernel compatibility with 'schedutil' and implement a fallback to 'ondemand' or 'performance' if unsupported.
</issue_to_address>
### Comment 4

</code_context>
<issue_to_address>
**suggestion:** The git-clean-branches function may delete branches that are not protected.
Consider updating the exclusion list to include any additional branches you want to protect from deletion.
```suggestion
git-clean-branches() {
git branch --merged | grep -v "\*\|main\|master\|develop\|release\|staging\|production" | xargs -r git branch -d
}
```

<code_context>
- ];
+ # Sandbox settings
+ sandbox = true;
+ restrict-eval = false;
+
+ # Trusted users
</code_context>
<issue_to_address>
**🚨 issue (security):** Disabling restrict-eval may reduce security in multi-user environments.
Allowing arbitrary code evaluation can expose the system to risks from untrusted users. Please review whether this aligns with your security requirements.
</issue_to_address>
### Comment 6
<location> `modules/nix-settings.nix:33` </location>
<code_context>
+ restrict-eval = false;
+
+ # Trusted users
+ trusted-users = [ "root" "@wheel" ];
};
</code_context>
<issue_to_address>
**🚨 issue (security):** Adding '@wheel' to trusted-users grants elevated Nix permissions to all wheel group members.
Verify that every wheel group member should have elevated Nix access, since this configuration enables privileged operations for all of them.
