All I see from your comment: With a hammer in hand, everything is a nail.

Or to be more specific: If Microsoft is directly or directly involved in OSS or standards, then it's all EEE/compromised.

GPT/UEFI are standards, they are not ruled by Microsoft nor do I even think it was sole written with Microsoft in mind, at best what I can find is that UEFI took the same architecture Windows has with EFI, that's about it.

systemd's only concern with well systemd, no one is stopping you from not using it, or I'm oh so curious how non-systemd distros are able to boot WITH UEFI + GPT.

- GPT partition uuid's with the "mixed endianess" from Windows COM: https://devblogs.microsoft.com/oldnewthing/20220928-00/?p=10...

- ESP is the FAT filesystem, developed in 1977 for DOS

- LFS vfat extensions so the ESP can have directory entries with lowercase letters or longer than 11 characters. This also pulls in the UCS-2 encoding. Stuff from Windows 95.

- EFI executables are actually windows PE executables

- ... which are hacked on top of a MS-DOS MZ executables (The "This program cannot be run in DOS mode" thing)

- ... and use the Windows64 calling convention

So formally, UEFI is not ruled by Microsoft. Somehow yet all this Windows/MS-DOS stuff ended up in it.

>GPT partition uuid's with the "mixed endianess" from Windows COM

From the wikipedia[1]:

>The binary encoding of UUIDs varies between systems. Variant 1 UUIDs, nowadays the most common variant, are encoded in a big-endian format.

>Variant 2 UUIDs, historically used in Microsoft's COM/OLE libraries, use a little-endian format, but appear mixed-endian with the first three components of the UUID as little-endian and last two big-endian, due to the missing byte dashes when formatted as a string

In other words, there are 2 variants, 2 is for Microsoft's COM/OLE, so it's not designed by Microsoft.

>ESP is the FAT filesystem, developed in 1977 for DOS

>LFS vfat extensions so the ESP can have directory entries with lowercase letters or longer than 11 characters. This also pulls in the UCS-2 encoding. Stuff from Windows 95.

FAT is not govern by Microsoft, despite them being the original author, and even then FAT32 patents have expired[2].

>EFI executables are actually windows PE executables

You would need to provide proper source for this, the only source I can only talks about boot loaders, which I would imagine is written with the OS in mind[3].

You are wrong on the UUIDs, Variant 2 is what Microsoft did and got standardized after the fact.

And here the history and current usage of the PE format: https://en.wikipedia.org/wiki/Portable_Executable

It was made for Windows 3.1.

If you read my comment or the Wikipedia page you'll see clear as day that varient 2 is meant for windows, so I dont get this correction.

And again that source doesn't give me any evidence of your claim.
