OS Version Detection + +The CLI automatically detects the OS version from the base image: + +```bash +# From scripts/exports.sh +export OS_VERSION="$(awk -F= '/^VERSION_ID=/ {gsub(/"/, "", $2); print $2}' /usr/lib/os-release)" +``` + +This version is then passed to the Jinja2 templates as `os_version`. + +### 2. Template Substitution + +The `os_version` variable can be used throughout the build process: + +```jinja2 +# In templates, you can use: +{{ os_version }} + +# For example, in Debian-specific templates: +RUN echo "deb http://deb.debian.org/debian trixie main" >> /etc/apt/sources.list.d/bluebuild.list +# Could become: +RUN echo "deb http://deb.debian.org/debian {{ os_version }} main" >> /etc/apt/sources.list.d/bluebuild.list +``` + +### 3.
