What is `python3-dnf-plugin-cow`

Installing this package enables a DNF plugin which changes the behaviour of librepo. Instead of downloading rpm files directly into cache before installation they will be “transcoded” into “extent based” rpms which contain all the constituent files of the rpm already uncompressed. This package depends on a version of rpm which includes /usr/bin/rpm2extents and the sub-package rpm-plugin-reflink which understands these “extent based” rpms and can install files without copying the underlying data. This package broadly assumes the root filesystem supports copy on write / reflink’ing. Today this means btrfs or xfs.
