# Generic x86_64 System

[![Hex version]( "Hex version")](

This is the base Nerves System configuration for a kiosk x86_64 system.

## Using

The most common way of using this Nerves System is create a project with `mix` and to export `MIX_TARGET=x86_64`.

Then, change the x86_64 system dependency to
`{:kiosk_system_x86_64, "~> 1.0"}`

See the [Getting started
for more information.

If you need custom modifications to this system for your device, clone this
repository and update as described in [Making custom

See the [example project]( for more info

## Root disk naming

If you have multiple SSDs, or other devices connected, it's
possible that Linux will enumerate those devices in a nondeterministic order.
This can be mitigated by using `udev` to populate the `/dev/disks/by-*`
directories, but even this can be inconvenient when you just want to refer to
the drive that provides the root filesystem. To address this, `erlinit` creates
`/dev/rootdisk0`, `/dev/rootdisk0p1`, etc. and symlinks them to the expected
devices. For example, if your root file system is on `/dev/mmcblk0p1`, you'll
get a symlink from `/dev/rootdisk0p1` to `/dev/mmcblk0p1` and the whole disk
will be `/dev/rootdisk0`. Similarly, if the root filesystem is on `/dev/sdb1`,
you'd still get `/dev/rootdisk0p1` and `/dev/rootdisk0` and they'd by symlinked
to `/dev/sdb1` and `/dev/sdb` respectively.
