Just a little fun project to experiment and learn more about operating systems.
- The entire OS tree is stored in
./root
Note: the kernel is referenced in
/boot/kernelto be used later with kexec when it is implemented. Just to mess around, I want to be able to replace the entire running kernel image with kexec instead of requiring a restart. I know it's unnecessary, but it's cool.
build.py creates a osimage.js file that, when loaded, parses the ./root filesystem hierarchy and data into the actual root filesystem and bundles the kernel & all libraries. I highly advise against editing osimage.js directly and instead using the already existing setup.
Of course, the core of the entire system that pulls everything together is the kernel
- Kernel architecture & syscalls are primarily influenced by FreeBSD and Linux, although its inner workings is almost entirely my doing.
- Driver system is a mix between Minix and my own implementation
- Init system is highly influenced by FreeBSD's rc
- Filesystem Hierarchy is a mix between FreeBSD and Minix, but it is primarily influenced by FreeBSD.
- Userland is made to behave like any other UNIX-like system, but where needed, it mostly follows the FreeBSD system of things.
