说明
cowbuilder is a wrapper around pbuilder that uses copy-on-write (COW) semantics for faster Debian package builds. Instead of creating a new chroot tarball for each build, it uses hard links to create a working copy, significantly reducing setup time. The tool creates clean, reproducible build environments for Debian packages. Each build starts from a pristine base system, ensuring packages build correctly without hidden dependencies on the developer's system. cowbuilder is commonly used for verifying package builds before upload to Debian archives, testing packages across different distributions, and CI/CD pipelines for Debian packaging.
