Fancy Sauce
Fancy sauce is a set of helper scripts for managing and deploying root file systems.
Features
- Build installed packages manifest using dpkg.
- Setup local signed apt repository for quick rootfs rebuilding.
- Deferred package installation using apt.
build_installed_manifest
Calling build_installed_manifest.sh will use dpkg -l to list installed packages and write the output to a file specified by
${CONFIG_MANIFEST_PATH}.
setup_gpg_key
This is a simple helper script to assist in setting up your GPG key to sign any custom packages.
It will setup the GPG key based on the ${CONFIG_GPG_KEY} setting. These options are documented at: https://www.gnupg.org/documentation/manpage.html
generate_repository
This script expects a manifest file to exist at ${CONFIG_MANIFEST_PATH}. The script will then proceed to download all the packages specified into
the ${CONFIG_DOWNLOAD_PACKAGES_PATH} directory and then add it to the repository using reprepro.
Custom packages can also be added to the repoistory using the ${CONFIG_CUSTOM_PACKAGES_PATH} variable.
It will setup the apt repository based ${CONFIG_DISTRIBUTIONS} setting. These options are documented at: https://mirrorer.alioth.debian.org/reprepro.1.html
install_later
This is a standalone script that sets up a package to be installed later.
Which involves telling apt to cache the package using apt-get -d install ${package}.
Cached packages are stored in /var/cache/apt/archives.
Each call to install_later also sets up a install later script at a given path.
An install later script is a simple bash script which has lots of apt-get install calls and
can only run once. Running once is controlled by a state variable saved at /var/lib/install-later/has_run.
