A suite of utilities to build a debian root filesystem and bootable image for the Raspberry Pi 2, model B.
## Utilities
- `mkrootfs` Build a debian root filesystem in the given directory
- `mkrootimg` Bundle a root filesystem into a bootable, binary image that can be flashed to an sd card.
Run any of the above utilities without arguments for additional information.
## Usage Example
The typical use-case, creating a bootable image involves the following steps:
1. Create a root filesystem in a temporary directory "tmprootfs".
mkrootfs --hostname=pi --release=stretch --ssh-key=/home/user/.ssh/id_rsa.pub tmprootfs
2. Pack the root filesystem into a binary image
mkrootimg tmprootfs pi2-stretch.img
3. Copy the image to an sd card.
dd if=pi2-stretch.img of=/dev/mmc0
4. Boot a Raspberry Pi from the card.
Note that several initialization tasks are performed during the first boot:
- the root filesystem is expanded to fill the whole sd card
- ssh keys and machine ids are regenerated
Progress will be signaled through the ACT and PWR LEDs:
- both leds will flash rapidly for a couple of seconds, indicating
that first-boot tasks are about to start
- PWR will blink in a "heartbeat" pattern and ACT will indicate sd card activity
- first-boot tasks are run
- after completion, the ACT led will blink in a heartbeat pattern an PWR will be turned off
## Requirements
- qemu-user-static
- qemu-debootstrap
