Generic x86_64 System

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

Please contact me about this if you're really interested in it. I don't maintain it, and unless you really dig through the code, it's not going to be obvious how it works. I'm happy to help if you're really interested.

Installation

Add nerves_system_x86_64 to your list of dependencies in mix.exs:

def deps do
    [{:nerves_system_x86_64, "~> 0.1"}]
end

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/rootdisk1, etc. and symlinks them to the expected devices. For example, if your root file system is on /dev/sdap1, you'll get a symlink from /dev/rootdisk1 to /dev/sdap1 and similar files for each partition. The whole disk will be /dev/rootdisk0.
