Aero is a new modern, experimental, unix-like operating system written in Rust. Aero follows the monolithic kernel design and it is inspired by the Linux Kernel and the Zircon Kernel. Aero supports modern PC features such as Long Mode, 5-level paging, and SMP (multicore), to name a few.
Is this a Linux distribution? No, Aero runs its own kernel that does not originate from Linux and does not share any source code or binaries with the Linux kernel.

Please make sure you have a unix-like host system before building Aero. If you are using windows, its highly recommended to use WSL 2.
Before building Aero, you need the following things installed:
rustcshould be the latest nightly
g++5.1 or later
The following are not requirements but are recommendations:
Beefier machines will lead to much faster builds!
The very first step to work on Aero is to clone the repository:
$ git clone https://github.com/Andy-Python-Programmer/aero $ cd aero
Aero uses a custom build system, that wraps
cargo and takes care of building the kernel and userland for you. It also builds the initramfs and disk image for you.
The main command we will focus on is
./aero.py. The source code can be found in the root of the repository and, as the file name states, it is written in Python.
By default if you run
./aero.py without any arguments it will build the kernel and userland in release mode with debug symbols and run it in QEMU. You can configure the behavior of the build system though. If you want to, you can use the
--help option to read a brief description of what it can do.
The build system acknowledges few different build modes, which cannot be used together and they are:
--clean option will clean all the build outputs.
--check will build the kernel and userland using cargo's
check command, this build mode will not produce a disk image, if you want one without actually running Aero in the emulator read ahead
--test will run the built-in Aero test suite
--document will generate web-based docs using cargo's
--sysroot will build the full userland sysroot. If not passed, then the sysroot will only contain the
aero_shell and the
Note: This command will require a relatively large amount of storage space. You may want to have upwards of 10 or 15 gigabytes available if building with full sysroot.
Each of these modes can be used with additional flags, that will alter the behavior in different ways, some of them will not work for some of these modes - for example: the
--la57 option will not have any effect when you are simply checking or documenting the build.
--debug toggles off the release build flag when calling cargo.
Summary: If the
--debug flag is not passed then it will build Aero in release mode and debug symbols will be avaliable. On the other hand, if the debug flag is passed then it will be built in debug mode and debug symbols will be still avaliable. By default Aero is built in release mode (with debug symbols) since it generates faster and smaller binaries which are easier to test.
--no-run prevents from running the built disk image in the emulator
--bios lets you choose the firmware the emulator will use when booting Aero, currently supported values are:
--features accepts a single comma-separated list of kernel crate features, please keep in mind that there cannot be spaces in between the values
--target lets you override the target architecture for which the kernel is built, currently the default value is
--la57 tells the emulator to use 5 level paging, if it supports it
The built disk image is stored in the
build directory under the name
aero.iso. Both the disk root and initramfs root are preserved in case you want to inspect them manually.
If you haven't used the
--no-run option and you aren't using the
--document build mode, the build system will run Aero in the emulator for you.
Want to give Aero a shot, without building it! You can go to the latest job and download the latest nightly image (
aero.iso), under artifacts.
