A related issue I still see very often, even with files newly created just this year, is when trying to extract zip files on my Linux systems that contain non-ASCII filenames and that were created on Windows systems, especially ones with apparently non-English locales like Japanese. Need to trial and error the locale I give to unzip and sometimes hack together fixed names with iconv until the mojibake seems to fix itself.
Btrfs doesn’t have encryption, so you need to do it with luks to an mdadm raid, and build btrfs on top of that. Luks on mdadm raid is known to be slow, and in general not a great idea.
Why involve mdadm? You can use one btrfs filesystem on a pair of luks volumes with btrfs’s “raid1” (or dup) profile. Both volumes can decrypt with the same key.
A standard called SystemReady exists. For the systems that actually follow its standards, you can have a single ARM OS installation image that you copy to a USB drive and can then boot through UEFI and run with no problems on an Ampere server, an NXP device, an Nvidia Jetson system, and more.
Unfortunately it’s a pretty new standard, only since 2020, and Qualcomm in particular is a major holdout who hasn’t been using it.
Just like x86, you still need the OS to have drivers for the particular device you’re installing on, but this standard at least lets you have a unified image, and many ARM vendors have been getting better about upstreaming open-source drivers in the Linux kernel.
My best guess: whatever they’re filing now was so exhaustively researched that it took months to prepare the strongest case they’re able to make, possibly delayed by the lawyers working on several other cases. Plus waiting until sales have dried up can maximize damages.
Another possibility is that Nintendo/TPC is planning to make some big Pokémon announcements soon and wants to target this shortly before their own new games to reduce competition. Palworld might seem like more of a threat to the execs now that Pokémon is nearing a major release than it was in the middle of a long drought for the series.
