<message>Add new documentation files for device DNS management via DHCP and dnsmasq configuration. Update cloud-init scripts to ensure proper handling of /etc/resolv.conf and DNS settings, allowing for seamless integration with file.server. Modify existing scripts to support dynamic LAN subnet configuration and improve overall network boot functionality. These changes enhance user experience and streamline the setup process for the CM4 eMMC provisioning service.

|
# Example: create user (pi), enable SSH, then download and run first-boot.sh to install
|
|
# Chromium kiosk, rpd-labwc, and touch options. Edit FIRST_BOOT_URL to point to your
|
|
# hosted first-boot.sh (e.g. file server or raw GitHub).
|
|
#
|
|
# 1. Generate a password hash: mkpasswd -m sha-512 'YourPassword' or openssl passwd -6 'YourPassword'
|
|
# Paste the full output into the passwd: line below.
|
|
# 2. Host first-boot.sh (same dir as this repo: cloud-init/first-boot.sh) at FIRST_BOOT_URL.
|
|
# 3. Optional: copy first-boot.conf.example to first-boot.conf, edit variables, and host it
|
|
# as first-boot.conf; then add a runcmd line to download it to /tmp/first-boot.conf before
|
|
# running first-boot.sh so the script loads your config.
|
|
# 4. To use a different username than "pi", set PI_USER in first-boot.conf and create that user below.
|
|
# 5. DNS: manage_resolv_conf: false and NM rc-manager=symlink so the device uses DNS from DHCP
|
|
# (LXC option 6) and file.server resolves. See docs/DEVICE-DNS-DHCP-RESOLVCONF.md.
