<message>Modify the first-boot.sh script to include an additional step for managing screen brightness during the provisioning process. Update user-data.bootstrap to improve DNS configuration by ensuring NetworkManager manages /etc/resolv.conf correctly, and remove obsolete scripts related to systemd-resolved. Enhance documentation to reflect these changes and clarify the setup process for users, improving overall network boot functionality and user experience.

# Minimal user-data: download bootstrap.sh from your file server and run it at first boot.
|
|
#
|
|
# 1. Host bootstrap.sh at a URL reachable from the device on first boot (e.g. your
|
|
# provisioning portal or file server). Example: http://10.20.50.1:5000/files/bootstrap.sh
|
|
# 2. Copy this file to the boot partition as "user-data" (with meta-data and optional network-config).
|
|
# 3. Edit BOOTSTRAP_URL below to match your server (or set it once in the runcmd section).
|
|
#
|
|
# DNS: Use NetworkManager rc-manager=symlink so /etc/resolv.conf gets DHCP DNS (LXC option 6).
|
|
# RPi OS does not use systemd-resolved by default. Ensure bootstrap.sh does not overwrite
|
|
# /etc/resolv.conf. See docs/DEVICE-DNS-DHCP-RESOLVCONF.md.
