### Setup stagesd
### Setup stages
Blinking leds show which phase the extroot setup scripts are in. Consult the
sources for details: [autoprovision-functions.sh](image-extras/common/root/autoprovision-functions.sh#L49).
#### Stage 1
#### Stage 1: setup extroot
At the first boot after flashing the firmware the autoprovision script will
wait for anything (!) in `/dev/sda` to show up, then erase it and set up a
`swap`, an `extroot`, and a `data`filesystem (for the remaining space), and
then reboot.

#### Stage 2
#### Stage 2: download and install some packages from the internet
Once it booted into the new extroot, it will continuously attempt to install
some OpenWRT packages until an internet connection is set up on the router
(either by using ssh or LuCI if you could include it in the firmware).
(either by using ssh or LuCI if you could fit it into the firmware).
### Login
After flashing the firmware the router will have the standard
`192.168.1.1` IP address, and SSH will listen (in all stages) using the keys
specified in [authorized_keys](image-extras/common/etc/dropbear/authorized_keys)
(**this repo contains my own ssh public key as an example, either delete it or replace
it with yours!**).

By default the root passwd is initialized to a random string. If
you want to set up a password, then edit the stage 2 script: [autoprovision-stage2.sh](image-extras/common/root/autoprovision-stage2.sh#L53).
By default the root passwd is not set, so the router will start telnet with
no password. If you want to set up a password, then edit the stage 2 script:
[autoprovision-stage2.sh](image-extras/common/root/autoprovision-stage2.sh#L53).
If a password is set, then telnet is disabled by OpenWRT and SSH will listen
using the keys specified in [authorized_keys](image-extras/common/etc/dropbear/authorized_keys).
Once connected, you can read the log with `logread -f`.

I've extracted this from a project where OpenWRT nodes auto-provision
themselves in 3 stages, but I thought it's useful enough for making it
public (stage 1: extroot setup; stage 2: install packages; stage 3: a
Python script for an app-level sync feature).

but it's easy to extend it.
