Kudos for doing so! This is seriously a great endeavor. Regarding its relation to UNIX concepts, I do spot a classical hierarchical file system there, though. ;) Is it only an "add-on" (similar to IFS on IBM i), or is it fundamental?

Thank you!

At this early stage, the filesystem exists only to prove the disk drivers and the IPC interfaces connecting them. I chose FAT32 for this since there has to be a FAT partition anyway for UEFI.

The concept of the VFS may stick around as a useful thing, but it’s strictly for storage, there is no “everything is a file” ethos. It’s entirely a user space concept - the kernel knows nothing of virtual filesystems, files, or the underlying hardware like disks.
