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 /mnt/data, then re-installs them on every boot

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

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
  

• The new package is exactly the old steps packaged in a debian package

• dpkg-build-files contains the scripts that build the package (using dh_make and debuild) if you want to build it yourself / change it

• Built on Ubuntu-20.04 on Windows 10/WSL2

Steps

1. Get into the unifios shell on your udm

   unifi-os shell
   

2. Download udm-boot_1.0.1-1_all.deb and install it and go back to the UDM

   curl -L https://raw.githubusercontent.com/boostchicken/udm-utilities/master/on-boot-script/packages/udm-boot_1.0.1-1_all.deb -o udm-boot_1.0.1-1_all.deb
   dpkg -i udm-boot_1.0.1-1_all.deb
   exit
   

3. Copy any shell scripts you want to run to /mnt/data/on_boot.d on your UDM (not the unifi-os shell)and make sure they are executable and have the correct shebang (#!/bin/sh)

   Examples:

   • Start a DNS Container 10-dns.sh
   • Start wpa_supplicant on_boot.d/10-wpa_supplicant.sh
