# Creation of a distribution based on poky-tiny
|
||
|
|
|
||
|
|
_poky-tiny_ is a distribution that is packed with Yocto and is aimed to provide a very minimal OS for embeded systems.
|
||
|
|
|
||
|
|
Its is built to fit on a 8MB disk, and goes down to 1.5MB when compressed.

|
## Layer
|
||
|
|
|
||
|
|
The distribution must be put in a layer.
|
||
|
|
|
||
|
|
Since Yocto layers are versionned, it is better to create a new custom layer containing the distribution, and eventually additionnal softwares, machines, etc.
|
||
|
|
|
||
|
|
## Distro config
|
||
|
|
|
||
|
|
`$LAYER/conf/distro/my-distro.conf`:
|
||
|
|
```sh
|
||
|
|
# Based on poky-tiny
|
||
|
|
require conf/distro/poky-tiny.conf
|
||
|
|
|
||
|
|
DISTRO = "my-distro"
|
||
|
|
DISTRO_NAME = "my-distro"
|
||
|
|
DISTRO_VERSION = "0"
|
||
|

# Install dropbear SSH server
|
||
|
|
IMAGE_INSTALL_append += " dropbear"
|
||
|
|
|
||
|
|
# Dropbear has also a feature to activate:
|
||
|
|
EXTRA_IMAGE_FEATURES = "ssh-server-dropbear"
|
||
|
|
|
||
|
|
# Install syslinux:
|
||
|
|
IMAGE_INSTALL_append += " syslinux"
|

```
