Photon reduces the burden and complexity of managing clusters of Linux machines by providing curated package repositories and by securing packages with GPG signatures. Photon OS is available in a variety of pre-built packages in binary formats. - [Examining the Packages in the SPECS Directory on Github](examining_packages_spec_dir.md) - [Looking at the Differences Between the Minimal and the Full Version](differences_between_minimal_and_full_version.md) - [The Root Account and the `sudo` and `su` Commands](root_account_and_sudo_commands.md) - [Photon OS Package Repositories](photon-os-package-repositories.md) - [Examining Signed Packages](signed-packages.md) - [Building a Package from a Source RPM](building-a-package-from-a-source-rpm.md) - [Compiling C++ Code on the Minimal Version of Photon OS](compiling-c-code-on-the-minimal-version-of-photon-os.md)
