Welcome to FrostWing, a lightweight and flexible operating system designed for x86_64 platform. This README will guide you through the process of understanding the overall concept of the FrostWing Operating System.

FrostWing's ELF loader supports x86-64 ELF interpreters and starts the program's
interpreter; dynamically linked programs must also have every DT_NEEDED
library available in the root filesystem. Build a musl-linked program with its
normal dynamic defaults, then stage it and its dependencies before creating the
root disk:
musl-gcc input.c -o input
./scripts/stage-elf.py ./input
make root-diskThe staging helper inspects ELF metadata without executing the input, copies the
program to fs_root/bin, and places its interpreter and recursive shared-library
dependencies under fs_root/lib or fs_root/lib64 according to the interpreter
path. make root-disk replaces the existing disk.img, so back up any data on
that image first. Review the staged files before distributing an image. This supports
musl-linked x86-64 programs to the extent of FrostWing's Linux syscall
compatibility; copying a glibc executable and its libraries does not make
arbitrary Linux/glibc programs compatible.

This operating system is real machine bootable and tested under the following circumstances:
Boot Disk information:
- Using 32 GB Pendrive
- GPT Disk (MBR Also works)
- Both BIOS / UEFI supported
- Ventoy loaded
- FrostWing.iso in the root directory
Important
It is recommended to use Ventoy because you will not have the risk of flashing and failing of USB-Drives.
