The kernel for LibertyOS.

Hi Daniel,

You asked if I could help you - sure, I can.

Probably github discussions is not the best medium for comms, so lets figure out what we can use - Telegram, Zulip, Discord, Matrix, or forum.osdev.org forums - anything works.

Is this a successful run? Built from latest main commit with cargo build --release; cargo run --release Same without release flag.

LIBERTY-OS
KERNEL VERSION 0.9.7

VirtAddr(0xb8000) -> Some(PhysAddr(0xb8000))
VirtAddr(0x201008) -> Some(PhysAddr(0x401008))
VirtAddr(0x10000201a10) -> Some(PhysAddr(0x27fa10))
panicked at `[ERR] HUGE PAGES ARE UNSUPPORTED`, src/mem.rs:37:43

If so, please, provide expected behavior in the README.md

In line 56 of src/main.rs there is an inefficient creation and population of a vector. This pull request improves this by creating and populating the vector with iterator collect instead of a for loop which pushes a number onto vector with each iteration. This optimization was originally noticed by reddit user NateReinarWoodwind.

This docker file documents the podman version of commands as that is what I used on Archlinux. The equivalent Docker commands should also work. The target/ directory was added to .dockerignore.

Added issue and feature request templates .gitignore would be nice too Updated README.md with "expected behavior"

Glad to contribute to LibertyOS kernel! Feel free to criticize, edit or request additional features/corrections to this PR I will update my issue to match new issue template after your approval

Is your feature request related to a problem? Please describe. The name LibertyOS is already taken by a linux distro advertising as the first blockchain operating system.

Describe the solution you'd like Find a new name.

Describe alternatives you've considered The alternative is not changing the name, but that would lead to confusion and this kernel's reputation might suffer by being associated with the distro mentioned above.

Additional context Reddit post on r/rust from 2021-12-15

Describe the bug When I tried building the kernel from the source when crates were building at the moment of compilation of lazy_static error: cannot find macroasmin this scope error appeared.

To Reproduce Steps to reproduce the behavior:

1. Build the kernel from the instructions on the Github page. The error happened when I ran cargo build

Expected behavior Expected that the kernel would build succesfully

Add a dockerfile so that LibertyOS can be built from a docker image. This will allow LIbertyOS to be built in a "container" so that all dependencies, etc will be built in the docker container and will not contaminate the host operating system. I will try to create a sample Dockerfile and post it here when I am done. I'm a beginner in dockerfiles, so maybe someone with more experience in docker can take a look at the file I post and suggest improvements.
