Well splitting hairs, it mandates that everyone support FAT, individual system+OS vendors can add their own filesystems, but then its vendor lock.
So, just do FAT and be done with it. Adding other filesystems is just a waste of time because the ESP only needs to store a half dozen files or so.
13.3.1.1:
"The EFI firmware must support the FAT32, FAT16, and FAT12 variants of the EFI file system"
- babypuncher 5y agoI think FAT is a fair baseline. It can be implemented in a few dozen lines of code. Support for it is ubiquitous. It is not encumbered by any active patents. All the alternatives I have seen proposed are both considerably more complex and not ubiquitously supported.
