cfdisk only changes the partition table, this table like a small paper that you store at the front (or back) of drive where you put information, it's just a list of coordinates like from this point to this point is your home, from this to this is your yard, from this to this is your neighbor.
Just because you changed the values on your paper doesn't actually make your neighbor closer or further.
System read this list to figure out where are the "borders" between different sections that you defined to load and use them logically for multiple file systems.
If it's Germany ... My best bet would be at the TV kable/streaming companies, but probably behind additional paywall.
AFAIK Germany regulations are strange, the stream copyright owner can broadcast video and later based on your IP send you a Bill to pay claiming unauthorized access.
That's why I stated that it should be illegal to promise product while selling a undefined time limited license, there should be a clear minimum time stated when you "buy a subscription" for (single player?) games.
I concur
Buyer should not gain rights to product, so they should not be allowed to profit from it, but they should be able to preserve it, unless the license that you actually buy had a time limitation, but that should be clearly stated when you buy it that you only buy access to it to (at least) X amount of time like you have with online subscriptions.
I would suggest to add those additional AP as soon as possible if going UniFi way, as adding more later might require to replace all units as we already saw multiple times with UniFi devices, as they are quick to deprecate old ones and make them not work with new ones.
I like the concept, you could also detect the compose file name automatically.
Or write down hashes for tag even if compose don't use your variables so reading from compose, so people would not need to relay on the script but could use it as additional backup
Sounds like a permission problem, probably when you did copy the files then permission did change from like www-data into your user, simplest solution would be to change the permissions for those files (for example to 777 as a temporary solution)
I had multiple issues with DVD drives that could write but then it would not work on any other DVD readers or don't work at all even on the writer drive. And other way around. They are just to damn delicate, especially those you have in your laptops.
I would try to write the disk with slower speeds as it could improve it somehow like less vibrations or more laser burns.
But in your case l would check if that person does have a TV or even DVD player that could read from USB, or buy them some smart set top box with jellyfin/Plex/Disney+/...
I'm not a specialist but to me, it is all about road quality, asfalt when you can safely drive and it's very smooth ride like you drive in the air, while co concrete you can drive well but there are clearly visible or audible bumps, so for me the actual material (or mix of them) doesn't matter, if they can make classy and safe to drive road with glass or anything else should not matter.
ALVR works on Linux with Quest 2, BeatSaber works fine, dont know much about other games.
