• Design a virtual file system (VFS) and implement it. The traditional UNIX VFS works and saves headaches when porting software, but you can make your own thing too.
• Implement a simple virtual file system like a memory-only tmpfs to avoid crippling the design of your VFS too much while implementing it alongside real storage filesystems.
• Decide how to abstract devices. UNIX likes usually go for a /dev virtual filesystem containing device nodes and use ioctl() alongside standard FS calls to do operations on them.
• Get a userland going by loading executables from your VFS and running them in ring 3. Set up a way to perform system calls. Write a PCI driver.
• Add support for a storage medium, the easiest and most common ones are AHCI and NVMe.*/
