Consider adding the lcdproc package to the base installation. VyOs is a great option for re-purposed older hardware firewall appliances like Watchguard Fireboxes, etc.. These machines typically have a front-facing LCD screen, sometimes with a keypad. Having support for LCDs would make VyOS that much more desirable for new users.
FWIW, the discussion threads for these appliances on the pfSense forum (including enabling the LCDs) attract hundreds of posts, and many thousands of reads. This seems like something people REALLY want to make work. There is something inherently attractive to the idea of running a firewall distribution on a purpose-made machine after it makes it's way out of a data center and into private hands.
Currently, the lcdproc package has to be installed in VyOS from the Debian packages. Then, a config file has to be created with the right driver and options. Last, the LCDd server and (one or more) clients have to be started as well. Other steps have to be taken to redo this after a restart.
A further step would be to integrate this whole setup within the VyOS command line for a complete integration.
Thanks for considering it.
