 For a faster feedback loop, sometimes you want to speed up debugging your `rootfs.cpio.gz` init script which is inside your (initramfs / initrd) image- which is typically a gzipped, `cpio` archive. The bootloader extracts and loads this `initramfs` / `initrd` filesystem, calling your `init` script first. In this repo example, we [pass](https://github.com/KarmaComputing/minimal-linux-boot-coreutils/blob/c64027b54b12d488f83cef75b5fbfee3d444e661/run-qemu.sh#L5C144-L5C154) `init=/init` to the kernel args. During boot the `init` file
 (which is stored in the root (`/`) of the `initramfs` image, is ran first. Distributions can use this to perform initial setup, such as ensuring
 a minimal valid linux directory structure (`/dev`, `proc` etc) and handle other boot-time kernel arguments such as `ip=` to set boot time network ip addressing. For example, if you're using  the [_alpine_ distro, their`initramfs``init` file
-parses the kernel `ip=` parameters in the following way](https://gitlab.alpinelinux.org/alpine/mkinitfs/-/blob/master/initramfs-init.in?ref_type=heads#L184-206). But you might choose to apply your own logic (ideally keeping to the `ip` syntax documented at [kernel.org/doc/Documentation/filesystems/nfs/nfsroot.tx](https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt#:~:text=ip%3D%3Cclient%2Dip%3E%3A%3Cserver%2Dip%3E%3A%3Cgw%2Dip%3E%3A%3Cnetmask%3E%3A%3Chostname%3E%3A%3Cdevice%3E%3A%3Cautoconf%3E%3A%0A%20%20%20%3Cdns0%2Dip%3E%3A%3Cdns1%2Dip%3E%3A%3Cntp0%2Dip%3E)- though as you can tell by searching online, distributions/documentation can vary so a) Check the distro source (e.g. [alpine's init ip parsing](https://gitlab.alpinelinux.org/alpine/mkinitfs/-/blob/master/initramfs-init.in?ref_type=heads#L184-206) of their packaged initramfs `init` file, or b), choose how to parse `ip=` yourself if you're building your own minimal linux kernel. In this `minimal-linux-boot-coreutils` repo, we package `busybox`, which, like alpine's `init` file, ships with its own logic which parses any applied `ip=` kernel parameter addressing

 To play around quicky with an already *built* `initramfs` / `initrd` image (for reference, [here's where we _build_ the initramfs image](https://github.com/KarmaComputing/minimal-linux-boot-coreutils/blob/c64027b54b12d488f83cef75b5fbfee3d444e661/build-rootfs.sh#L7)). But building a brand new image etc takes time, for instance, we [compile `busybox` and `openssh`](https://github.com/KarmaComputing/minimal-linux-boot-coreutils/blob/c64027b54b12d488f83cef75b5fbfee3d444e661/build-all.sh#L26-L35) into our`initramfs`.
