## Other Notable Changes {#sec-release-21.11-notable-changes}
- The linux kernel package infrastructure was moved out of `all-packages.nix`, and restructured. Linux related functions and attributes now live under the `pkgs.linuxKernel` attribute set.
In particular the versioned `linuxPackages_*` package sets (such as `linuxPackages_5_4`) and kernels from `pkgs` were moved there and now live under `pkgs.linuxKernel.packages.*`. The unversioned ones (such as `linuxPackages_latest`) remain untouched.
- The setting [`services.openssh.logLevel`](options.html#opt-services.openssh.logLevel) `"VERBOSE"` `"INFO"`. This brings NixOS in line with upstream and other Linux distributions, and reduces log spam on servers due to bruteforcing botnets.
However, if [`services.fail2ban.enable`](options.html#opt-services.fail2ban.enable) is `true`, the `fail2ban` will override the verbosity to `"VERBOSE"`, so that `fail2ban` can observe the failed login attempts from the SSH logs.
