I guess I'm the kind of person that can spot a systemd screen from across the room now

The thing that gets me is that they seem to have a separate machine for each display

Every one of them is running a crypominer

Probably there for "easily changing out logos of different flavor instead of using paper/plastic printout"

Not just to show the logo, but to run the entire machine. Probably IoT enabled, so monitoring and maintenance actions and OTA are important enough that it’s worth having a very slim version of Linux on there instead of taking the security risk of building up from a lower level.

I've never seen one of these, but I assume it performs other functions - surely monitoring sensors, probably reporting that data, maybe allowing triggering maintenance functions, etc.

That said, processing and storage is so cheap on this scale that it's probably better (and cheaper) to go with a tried and true, widely supported system, than it is to optimize with custom hardware/firmware.

a whole linux system isn't even all that crazy. if it runs doom it can probably also run linux so probably everything from a potato to a dog's left testicle can run linux.

200ml tequila 400mg ritalin 3mg lsd 3 scoops vanilla(? Need help with the flavor) ice cream 200ml milk or plain yogurt

Salt rim with cocaine and ascorbic acid sip gently.

Edit: do not drink this. This is the second most dangerous coctail recipe I've ever written.

Or at least how to run DOOM on it.

The flash memory the OS is stored on is borked.

Filesystem check shows dependency errors attempting to check ext4 fs on /dev/mmcblk0p2. Assuming ext4 and fsck are installed (it should be if this isn't a mega-custom ultra stripped down private distribution) this shouldn't be possible.

Further down networking fails to initialize leading to a bunch of fails before it succeeds and reaches its target, only to be stopped by the dependency errors again.

You'd think a damn sticker would be good enough

It's failing storage, top half of the display is EXT4 complaining it can't read the SD card, bottom half is the result of that, services can't start.

And it probably should be. We could even have a set of small plates embedded somewhere for quick swapping on demand.

I like computers, but having an individual computer to run a single drink display really is overkill. At least use one to drive all the labels simultaneously, if you still want the ability to display nifty animations of liquid flowing above the actual liquid actually visibly flowing.

Uncontrollable urge to tell people to install Linux.

I hate to break ot to you, but this is a linux drink. All that will you'll get is a kernel panic
