Update cloud-init scripts and documentation for enhanced DNS management and provisioning steps</message>
<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.

# Deploy screen-brightness daemon to an existing reTerminal DM.
|
||||
#
|
||||
# Usage:
|
||||
# On device (local files in current directory):
|
||||
# sudo ./deploy-screen-brightness-to-device.sh
|
||||
#
|
||||
# On device (download from file server) — use ONE of these (sudo often strips env):
|
||||
# sudo ./deploy-screen-brightness-to-device.sh "http://file.server:5000/files"
|
||||
# sudo -E BOOTSTRAP_URL="http://file.server:5000/files" ./deploy-screen-brightness-to-device.sh
|
||||
#
|
||||
# From host (deploy via SSH; repo files used from ../cloud-init/fileserver/):
|
||||
# ./deploy-screen-brightness-to-device.sh [user@]hostname
|
||||
#
|
||||
# From host via jump server (bastion):
|
||||
# SSH_JUMP_HOST="user@jump.example.com" ./deploy-screen-brightness-to-device.sh pi@10.0.0.5
|
||||
# Or in ~/.ssh/config set ProxyJump for the device; then no env var needed.
|
||||
#
|
||||
# Does not overwrite existing /etc/screen-brightness.conf (keeps vessel tuning).
|
||||
# See docs/SCREEN-BRIGHTNESS-MANUAL-SETUP.md for full manual steps.
