UDM / UDMPro Boot Script

Features

1. Allows you to run a shell script at S95 anytime your UDM starts / reboots
2. Persists through reboot and firmware updates! It is able to do this because Ubiquiti caches all debian package installs on the UDM in /data, then re-installs them on reset of unifi-os container.

Compatibility

1. Should work on any UDM/UDMPro after 1.6.3
2. Tested and confirmed on 1.6.6, 1.7.0, 1.7.2rc4, 1.7.3rc1, 1.8.0rc7, 1.8.0+

Upgrade from earlier way

• As long as you didn't change the filenames, installing the deb package is all you need to do. If you want to clean up beforehand anyways....

  rm /etc/init.d/udm.sh
  systemctl disable udmboot
  rm /etc/systemd/system/udmboot.service
  

• build_deb.sh can be used to build the package by yourself.

  • dpkg-build-files contains the sources that debuild uses to build the package if you want to build it yourself / change it
  • by default it uses docker or podman to build the debian package
  • use ./build_deb.sh build to not use a container
  • the resulting package will be in packages/

• Built on Ubuntu-20.04 on Windows 10/WSL2

Install

You can execute in UDM/Pro/SE and UDR with:

curl -fsL "https://raw.githubusercontent.com/unifi-utilities/unifios-utilities/HEAD/on-boot-script/remote_install.sh" | /bin/sh

This is a force to install script so will uninstall any previous version and install on_boot keeping your on boot files.

This will also install CNI Plugins & CNI Bridge scripts. If you are using UDMSE/UDR remember that you must install podman manually because there is no podman.

Manually Install Steps

1. Get into the unifios shell on your udm

   unifi-os shell
   

2. Download udm-boot_1.0.7_all.deb and install it and go back to the UDM. The latest package will always be found at https://udm-boot.boostchicken.dev

   curl -L https://unifi.boostchicken.io/udm-boot_1.0.7_all.deb -o udm-boot_1.0.7_all.deb
   dpkg -i udm-boot_1.0.7_all.deb
   systemctl enable udm-boot
   exit
   

3. Copy any shell scripts you want to run to /data/on_boot.d on your UDM (not the unifi-os shell) and make sure they are executable and have the correct shebang (#!/bin/bash). Additionally, scripts need to have a .sh extention in their filename.

   Examples:

   • Start a DNS Container 10-dns.sh
   • Start wpa_supplicant on_boot.d/10-wpa_supplicant.sh
   • Add a persistent ssh key for the root user on_boot.d/15-add-root-ssh-keys.sh
