Do you want the box to display or a hard copy of the installer?
If the latter I’m sure I’ve seen them for sale in the past couple of years on distro websites. Click “get [distro]” and its some secondary item to downloading which is what most people went. Might be a USB key or disc.
If you want an actual box idk how they are shipped.
There is a keyboard shortcut to reload the config. I don’t remember what the default is. On the kitty website, go to the page about kitty.conf and ctrl-f reload or refresh.
To check that the config is really reloading, make an edit to the section about theme, tab style, etc.
There is a way to output the actual config as used so you can look for your settings.
If you call kitty from the command line you can optionally use an argument to specify a config file. Iirc it is --config but verify in docs.
What is the location of the config file you are editing?
Post the section of the config file that isn’t working?
Try moving the section you are editing to the very bottom of the file to ensure it isn’t getting over rided later on.
How curious. Are you doing a play?
You might have to DIY one if you don’t want an old one. Certainly there are websites you could upload a PDF to that would print for you.
I think the boxes made sense when they were for sale in a brick n mortar store because they are harder to steal and make the person feel like they are buying something when digital goods weren’t such an instinctive idea. I doubt they would be shipped because they are big for no reason and would require a lot of packaging to keep from getting wrecked in transit vs a USB key in a bubble envelope.
To buy linux in a box, you would have to find somewhere near you that is selling it in person. A computer store, a book store. Maybe a campus bookstore? They have a captive audience so sometimes can get away with stuff that doesn’t otherwise make business sense.
