Rudder

I've been updating aptPackageManager, zmdPackageManager, zypperPackageManager, fileManagement, checkGenericFileContent, copyGitFile, dnsConfiguration and sshConfiguration

For check generic file content, I decided not to hide by default the content of the file, since it look like it depends on too many checkbox

Applied in changeset commit:5b25c883f11669adb8fe1ed6c8ebc7d35c8715cf.
