Debian: without sytemd
If you run Debian Servers, you read last weeks about security problems of systemd service manager. On several tests i have seen much systems having problems on service starts on boot like on debian, raspian ..

Linux: Systemd ignore console-setup settings
If you work on older Laptops and you use a Console only System Setup like on Debian there is a Bug on systemd and the console-setup package since years. After reboot all Font Settings seems gone.
